Love that people are working with The forgotten but not un loved 3.8 V6. The big issue here as we all know is the glass transmission. In the day when I had my MKIII VR6 Jetta(n/a highly modded cams, BVH/P&P, intake manifold, etc.)I always thought The GTP was a beast.
Those 3800's can take some abuse, but need some mods to support higher horsepower builds. ZZPerformance sells a modified oil pump spring that helps keep the oil pressure up. Ring gaps are too tight from the factory and need to be opened up to support higher boost levels. Throw on an intercooler and the motors make great power. I run solid 12's with mine on pump gas and a conservative tune so I don't blow the transmission.
Richard, thanks for continuing to explore options on the 3800 engine. With how far our community has pushed them, it's fun to see some comparisons of various things at different levels.
Richard, you should check out some of our Aussie builds. Quite a few 400+whp setups and even one that has cracked the 500whp mark on a gen3 m90. Even got a guy pushing close to 600whp from memory with a larger yt 2300 blower. Hit up brushworks slick sixes for their cam and ported blower. Best in Australia with our l67s
That rising boost curve after 5000 rpm might mean you need some ported heads along with more cam. Looking forward to seeing the water or meth injection results!
Which is better for supercharging, the series one or two vn engine, also I'm really unsure about the manifold I can use as I have a Yella Terra charger with reverse snout. Any info is much appreciated.
@@stevewarnock919 in order to supercharge the vn 3800/L27 you would need a series 1 l67 manifold from the states, the only difference between series 1 and 2 vn engines other than the intake/pcv stuff is rear main seal type and the cam and cam gear/retention, I prefer the series 2
All these videos and the priceless info in them i love it. These other guys engines even better, and even better still you're testing using E85, water meth and mods that drop boost/charge temps but up in output its like dyno video heaven. keep em coming.
Best show yet, #Rich ... Best sounding 3800 that I've ever heard, even though there was more horse power to be had. Can't wait see you break 400 horses with basically this same setup - no turbo. 💚
Running 15psi using a 2.9 pulley. Had to add a intercooler and ice box. I always tell people if they race a supercharged 3800 car and lose just keep trying cause the more heat the slower they get. The second run is never as fast as the first. One hit wonder engines, atleast with the non intercooled m90. GM never shoulda let these engines leave non intercooled.
When you get the heads off, get the guide posts machined down so you can get .600 lift in there. A cam in the 230s with .580ish lift will net some decent gains. Especially turbo.
I come across these SC's about once a year at my pick and pull and always think I'm getting something crazy for the money ($50) but then I end up getting rid of them a few months later for like $80-100 since I don't have any small displacement motors
The thing I would really like to know is how this would affect MPG. Doing dyno work is always cool to see the results but we all know, we don't run our engines at WOT under max load all the time. Yes getting more peak HP and TQ makes us smile and maybe something else un mentionable but we need to be emissions minded, and mileage minded as well. Then there is the issue of dependability also as this video brings out. Who wants or can deal with knocking bearings and cranks out frequently. For Richard to be able to just go out and source another engine to grenade is fine for him I guess but eventually it will come when they are not so easy to find, even though they were produced along the comparison of the VW Beetle.
My Supercharged 2004 Buick Park avenue Ultra needs 93 to 99 no ethanol blended fuel. My owners manual states that any ethanol blended gas can damage to the block and supercharger and no regular 87 as it will knock heavy.
Since buying an l67 I’ve figured you don’t buy them for power unless you’re ready to spend more than what it would cost to just block off the pulley and run a turbo through it
Them 3.8s are sleepers!! My brothers and I bought a gtp off the auction and we have it on a 150shot and e85 and that thing is unexpected on the streets
The factory cam is smog-limited. None of these cam swaps that Mr. Holdener does can survive CA's biennial smog testing. Set up an LLC and register your car in Montana! [No smog tests; all MT's smog rolls downhill to end up in Nebraska... 😁]
Hi 👋 👋 👋 👋 Richard anyway I thought the test went well. But I was wondering if you would of used a cam bushing so you could advance the cam 12 degrees. And if it is advanced to much you can go into the programming of the factory complex and adjust it. This is only an idea only. I have no idea if it would work. Oh can't wait until you do the next test on that engine thanks Ray
As always I learned a lot , one thing for certain I'm going to wrap the longtube headers on my heads , cam intake LS1 even though it is na , it will be fun to compare before & after temps , thanks Richard......
A narrower LSA would build more torque at a lower RPM and fall off at higher RPM, but it’s less necessary with supercharged stuff since the boost already makes more power down low. More torque probably isn’t ideal since most applications that use this motor are FWD and most of the trans “behind” this motor don’t like the stock , let alone the extra torque of a hot rodded one. Torque tends to be the thing that kills parts; both driveline and engine. Look at his Big Bang series, where he’s stated that loading in lots of boost early likely caused the Gen 3 5.3 to fail. It’s also the reason people don’t spray nitrous at low rpm. A “150hp” shot makes 150 lb/ft at 5250 RPM, but makes 300 lb/ft at 2625 RPM.
110 would be good on it with a couple degrees of advance be a good little cam. When people know they won't be running an intercooler 215-230 favouring exhaust and 110-112 is common.
@Richard, would you be willing to try upgrading the bearings in the block that spun one? I was part of a group of dudes in high school who were really into these engines and we found the stock crank bearings to be a limiting factor. If I remember correctly, we were using Clevites.

@@richardholdener1727 yes, if possible.... I know a lot of the comments are old but I'm very curious on what kinda power I was actually putting down. I was running 18° timing and 42# injectors on 93 Oct.
@@bigredhelland that is correct they use the small chevy bell housing patter. So in a 4 banger or 2.8 s10 it'd be an easy swap. With my 4.3 it would need an adapter and was a reason to not use it. Ls swap the world
@@danielpeterson2843 I’m right there with ya. I just picked up a awesome blazer extreme bone stock in nice shape, 4.3. Going to ls swap it but I bought all the parts for a 3.8 like in this video for a different project that I decided to spice up and do rwd and ls swap (turbo) instead. So now I have a pile of parts to do a 400hp 3.8 that I’m sitting on.
i looked into doing this to a 3800 years ago and came to the conclusion the transmission can not handle that kind power for any length of time. the only path to fix the issue is to modify a FWD Cadillac transmission to replace the 4T65-HD transmission.
@@SupraBdub from what i understand the 4T65-HD comes with most, if not all, GM supercharged 3800 vehicles... but my point was at the end of the day you'll be spending big money to beef-up the powertrain.
Great video Richard! Any correlation between ignition timing and EGTs. I understand the timing was tuned for max HP, however I question if more timing (30deg+) would reduce the EGTs/glowing headers. Thank you.
Hi Richard. do you mind if I pick your brain. you've inspired me to do a budget turbo project. I'm using a ford laser with a 1.6L Mazda ZMDE engine and an eBay T25 turbo. it has a 2" compressor outlet. most of the cheaper intercooler and piping are 2.5" , would there be a problem using a 2- 2.5" silicone adaptor and 2.5 intercooler and piping? Thank mate. Richard from Australia.
It would probably be more like the down low power gain because it is really only increasing lift not duration so probably wouldn't make as dramatic of a difference up top
The MP90 is based off a Gen3, if I recall... The GenV is an overall better design, with the larger outlet at the bottom of the V, and a more open inlet leading into the rotor pack. Even ported Gen3's didn't perform as well.
@@james10739 The Magnuson mpx is a blower rotor housing with a larger inlet and outlet than a gen 3 or gen v case however it accepts the traditional m90 rotor packs be it from a super coupe or a gtp m90. It has a typical 4 bolt flange like the Thunderbird m90 but is designed for much higher blower speeds at much less output temp.
@@dezldave961 Ive seen they boast improvements with the mpx case over even Allen's m90s gen V blower on the 4.6 mod motor kits. They usually are worth 20-30hp over a worked gen V all with less output temps. The case lists for around 450$ i think too.
@@madmod Roger that, but I don't think I'd be too impressed with a 4.6 guy spinning an M90. Heck, I've got an MP112 sitting on top of my spare 3800 waiting for a rainy day, because it works like a champ.
Yes more power less boost equals less heat more efficiency less fuel usage more horsepower... More supercharger more camshaft... UA-cam Gail Banks killing a Duramax...
@@richardholdener1727 I forget. He maxed out the stock turbo, maxed out the stock injectors, and increased the exhaust pipe size, made a lot more HP, less boost, less fuel lower egts. I've been following the series killing a Duramax. So a bigger turbo, bigger injectors more air through the intake more air through the exhaust , made a ton more power and used less fuel... Great videos 👍
Mr Holdener,I need your help .I'm trying to maximize HP with the parts I have . Need to know what heads to add to mix for total maximization. This is what I have. (Elgin - 1840p / Fast lsxr -102 , timing chain , smaller crank pully ,high vol oil pump. Headers longtube .I'm looking to match what I all ready brought to a great pair of heads. What do you recommend ? ( going in an Corvette ls1 2000 frc. Manual) Thanks again for your time 🙏.
If you can drop those IAT's can you throw more timing at it and drop those EGT's even further? Man, I was worried about my blower car seeing 120°F IAT but after seeing this I am quite pleased haha.
Can you put this supercharger on a 2000 ls1 ? This motor was a corvette motor built for twin- turbos I took off the turbos because they needed new seals everything else still on the car.
The problem isn't the 3.8l engine its the trans. Thr transmissions are utter garbage and break like gass. Only if have a manual transmission and preferably rear wheel drive are there aftermarket options to handle the power. You do a 3.8l power upgrade you'll be blowning through transmissions every year. And are now 25 or more years old there very little options to up grade or junk yard transmissions anymore.
Hi I have a L67 in a Fiero it’s a fully built engine. I have an inter cooler and I’m using the North Star tb. I have a 3.6 pully we did a tune I got 345 whp my tuner did not do any timing. When I got home I saw we are at 12 degrees in all rpm range. I have the hp tuner set up. I want to change the pully to the 2.8 and re tune with timing. Also I am running E85. My tuner said the IAT should be relocated from the TB to the manifold. I guess I have to drill the manifold. Is that what you did ? And do I use the North Star IAT in the manifold so I make sure I have the same values and leave the other one in the TB just unplugged ?
Water-meth tests will be awesome, I'm curious for the same reasons I still think you should reference boost from the intake manifold! Should let the turbo sing more
The testing for this 3800 kinda dropped off. Been almost a year now lol. The chat across some of the 3800 groups were wondering what happened. Some were expecting a lot just because the LS stuff does, but I understand that's unrealistic to
Richard, I noticed when you showed the charts for the boost curves, and the fluid air temps, that in the chart titles it said "comp cam SC water meth base22". What was this about? I didn't hear anything in this video of the mention of water meth being used. Although in a previous video I remember hearing you wanted to test water meth injection into the blower. Was this a typo in this particular chart, or? I can't imagine charge temps ever reaching that high while spraying water methanol, unless your weren't spraying enough.
So am I good with my setup or should I drop pulley size on my 3800sc intercooled with zzp xp hot cam. Stock heads, 130 springs, ls7 lifters, on a 3.4 pulley the car feels great but wondering if it's a huge difference to goto a 3.2 pulley or am I staying in a good curve at 3. 4 pulley
I would kind of like a little more data from this test. Even if its just lambda and bsfc i can figure the airflow and find out where on the compressor flow map it might be. This is really close to where the blower is rated to spin and with the 100hp pirate riding the belt on the front of the engine it makes me wonder how good the m90g5 is. Like, they suck a lot and leak like crazy and need too much power to turn but 380hp is still 380hp even if it appears to be above the rated flow capacity of the blower.
@@richardholdener1727 its right at the edge. The factory bottom pulley is 6.96(?) and with a 3.2 blower pulley and 6400 rpm the blower is at 13,920 rpm. I cant find a flow chart that shows this blower rated to go over 13,500. Its not so obvious. I cant find what the efficiency of this blower is at this blower speed and pressure ratio. Eaton never tested it. Do you have injector PW and Lambda? I cant find a source that says these blowers are rated above 14k rpm. The bearing in the nose is rated at 20k. The engine itself isnt rated to go to 6400rpm. I dont know what the maximum m3/h that these blowers will move is.
@@jarredsmith8091 Cams should be picked based on where you want to make power. Regardless of engine build an 8.5-1 engine and a 12.5-1 engine of the same displacement will make power in a similar power band with the same cam. Same goes for cylinder heads. Anyone thats got real life experience or has watched many of richards videos knows that.

are you asking if I can dyno test your motor combo?
@@richardholdener1727 yes, if possible.... I know a lot of the comments are old but I'm very curious on what kinda power I was actually putting down. I was running 18° timing and 42# injectors on 93 Oct.
Would love to see a test of a w2a intercooler.
I was interested in these motors a few years back for an s10 swap. Went ls
Don’t these use a different bell housing pattern than the LS or 4.3? Or did yours have the 4cyl?
@@bigredhelland that is correct they use the small chevy bell housing patter. So in a 4 banger or 2.8 s10 it'd be an easy swap. With my 4.3 it would need an adapter and was a reason to not use it. Ls swap the world
@@danielpeterson2843 I’m right there with ya. I just picked up a awesome blazer extreme bone stock in nice shape, 4.3. Going to ls swap it but I bought all the parts for a 3.8 like in this video for a different project that I decided to spice up and do rwd and ls swap (turbo) instead. So now I have a pile of parts to do a 400hp 3.8 that I’m sitting on.
@@bigredhelland mines actually a 92 Olds bravada, same thing but I'm about to pull the lm7 out and drop in an lq9
i looked into doing this to a 3800 years ago and came to the conclusion the transmission can not handle that kind power for any length of time. the only path to fix the issue is to modify a FWD Cadillac transmission to replace the 4T65-HD transmission.
You can get the 4t65hd built also.
@@SupraBdub from what i understand the 4T65-HD comes with most, if not all, GM supercharged 3800 vehicles... but my point was at the end of the day you'll be spending big money to beef-up the powertrain.
Need to do one of these videos with the ford 4.2l v6
I'd like to see you put all that supercharger kit on a na 3800 and see their max potential
Be the same results as long as the N/A engine had the same heads as the supercharged version which it probably doesn't
Can you do a test on a stock S/C 3800 with the rocker arm upgrade?
Great video Richard! Any correlation between ignition timing and EGTs. I understand the timing was tuned for max HP, however I question if more timing (30deg+) would reduce the EGTs/glowing headers. Thank you.
USUALLY IT DOES DECREASE EGT WITH MORE TIMING BUT 30 DEGREES UNDER BOOST IS NOT GOOD
That comp cam is similar to the BTR torque cam. It should have been installed factory.
What’s the biggest blower you can swap onto those motors?
Guys have done m112s.
I want a racing cup where everyone puts these in some crazy f1 looking kit cars
Hi Richard. do you mind if I pick your brain. you've inspired me to do a budget turbo project. I'm using a ford laser with a 1.6L Mazda ZMDE engine and an eBay T25 turbo. it has a 2" compressor outlet. most of the cheaper intercooler and piping are 2.5" , would there be a problem using a 2- 2.5" silicone adaptor and 2.5 intercooler and piping? Thank mate. Richard from Australia.
WE DO IT ALL THE TIME-IT WILL WORK
Richard -very cool t-shirt
Definitely excited to see the water meth testing 👍
Ya that always seems like a good idea for a roots blower especially if not intercooled
@ Richard Holdener/ what is the L32/L67 mean. What if you even the number 67/67
engine designations by the factory-early and late sc 3800
Sounds like cheap fun to me! Wrecking yards are full of these engines and can be had for a song and dance.
I'm happy with this . Great engine .
Great video would like to see the gains of 1.9 rockers on stock cam if would get you 20hp gain as cam gets you 40hp ?
It would probably be more like the down low power gain because it is really only increasing lift not duration so probably wouldn't make as dramatic of a difference up top
Im tempted to pick up a MP extreme m90 case. They are so affordable and should be worth good power over a stock gen3 case.
What is that extreme I mean obviously it's a supercharger but why did they come on
The MP90 is based off a Gen3, if I recall... The GenV is an overall better design, with the larger outlet at the bottom of the V, and a more open inlet leading into the rotor pack. Even ported Gen3's didn't perform as well.
@@james10739 The Magnuson mpx is a blower rotor housing with a larger inlet and outlet than a gen 3 or gen v case however it accepts the traditional m90 rotor packs be it from a super coupe or a gtp m90. It has a typical 4 bolt flange like the Thunderbird m90 but is designed for much higher blower speeds at much less output temp.
@@dezldave961 Ive seen they boast improvements with the mpx case over even Allen's m90s gen V blower on the 4.6 mod motor kits. They usually are worth 20-30hp over a worked gen V all with less output temps. The case lists for around 450$ i think too.
@@madmod Roger that, but I don't think I'd be too impressed with a 4.6 guy spinning an M90. Heck, I've got an MP112 sitting on top of my spare 3800 waiting for a rainy day, because it works like a champ.
Yes more power less boost equals less heat more efficiency less fuel usage more horsepower...
More supercharger more camshaft...
UA-cam Gail Banks killing a Duramax...
I know Gail, but what cam did he use in DuraMax?
@@richardholdener1727 I forget.
He maxed out the stock turbo, maxed out the stock injectors, and increased the exhaust pipe size, made a lot more HP, less boost, less fuel lower egts.
I've been following the series killing a Duramax.
So a bigger turbo, bigger injectors more air through the intake more air through the exhaust , made a ton more power and used less fuel...
Great videos 👍
@@richardholdener1727 killing a Duramax part 15..
GALE, I think ? 🤔
Why did they ditch the turbo for the sc, since the latter has no ic. Sc's more $$$ I'd imagine too
Mr Holdener,I need your help .I'm trying to maximize HP with the parts I have . Need to know what heads to add to mix for total maximization. This is what I have. (Elgin - 1840p / Fast lsxr -102 , timing chain , smaller crank pully ,high vol oil pump. Headers longtube .I'm looking to match what I all ready brought to a great pair of heads. What do you recommend ? ( going in an Corvette ls1 2000 frc. Manual) Thanks again for your time 🙏.
PORTED 243 HEADS OR AFR OR TFS
Yokes. 1437f is cooking. I get out of it at 1350 on my diesel and it's iron headed.
These engines are good gm should have just built them up with more power. From factory
If you can drop those IAT's can you throw more timing at it and drop those EGT's even further? Man, I was worried about my blower car seeing 120°F IAT but after seeing this I am quite pleased haha.
I have the bottom port and m90 supercharger my 3800 is a n/a do i need the supercharged heads with pcm or just heads
Can you put this supercharger on a 2000 ls1 ? This motor was a corvette motor built for twin- turbos I took off the turbos because they needed new seals everything else still on the car.
it is too small
Thanks Richard
What did blowing boost through that charger do id like to see boost gauges in diffent spots like before and after the blower
with the turbo? The turbo supplies 7 psi and this gets multiplied by the blower
This needs to go into the Nova
The problem isn't the 3.8l engine its the trans. Thr transmissions are utter garbage and break like gass. Only if have a manual transmission and preferably rear wheel drive are there aftermarket options to handle the power.
You do a 3.8l power upgrade you'll be blowning through transmissions every year. And are now 25 or more years old there very little options to up grade or junk yard transmissions anymore.
This is all good information for me. I need to know this.
great vid no fault on that , shows the useral a mild cam and longtube headers goes a long way ;)
aren't these 3800 motors configured as front wheel drive? Can you use these on a RWD car?
yes-they cam na in rwd camaros
They are used in rwd commodores aswell
Hi I have a L67 in a Fiero it’s a fully built engine. I have an inter cooler and I’m using the North Star tb. I have a 3.6 pully we did a tune I got 345 whp my tuner did not do any timing. When I got home I saw we are at 12 degrees in all rpm range. I have the hp tuner set up. I want to change the pully to the 2.8 and re tune with timing. Also I am running E85. My tuner said the IAT should be relocated from the TB to the manifold. I guess I have to drill the manifold. Is that what you did ? And do I use the North Star IAT in the manifold so I make sure I have the same values and leave the other one in the TB just unplugged ?
I ran it with a Holley ECU-not a stock ECU-I didn't use the IAT sensor-345 whp with a 3.6 pulley and 12 degrees of timing? Something doesn't add up!
@@richardholdener1727 I’m sorry I was wrong it’s a 3.2 pulley
I am thinking of going 2.8 do you think that’s to low
Egts are just a number
I never knew these were pushrod
3800 series best motor ❤
I wonder if you could put this supercharger one the 292?
Love the shirt Richard!
BA DUM
can i put a 3800 supercharged series 3 motor in my 3800 series 2 non supercharged grand prix do i have to change anything
ecu and harness are likely different
I would love to see a shootout between this and a supercharged ford 3.8 out of a supercoupe thunderbird.
Supercoupe was around 310 stock and the chevy was what 340 stock so I'd say that sums it up
@@jonathanlawson4667 what is the source of your info if you don't mind me asking?
@@christopherpentland5375 just the factory specs for both engines
@@jonathanlawson4667 but if we only wanted factory specs we would not watch this UA-cam channel.
310 hp-no sir! I think you meant 210 hp, 3800 was 240 hp and the series 3 was 260 hp
How much does l32 supercharger on l67 (240hp) add?
Water-meth tests will be awesome, I'm curious for the same reasons
I still think you should reference boost from the intake manifold! Should let the turbo sing more
The testing for this 3800 kinda dropped off. Been almost a year now lol. The chat across some of the 3800 groups were wondering what happened. Some were expecting a lot just because the LS stuff does, but I understand that's unrealistic to
Richard, I noticed when you showed the charts for the boost curves, and the fluid air temps, that in the chart titles it said "comp cam SC water meth base22".
What was this about? I didn't hear anything in this video of the mention of water meth being used. Although in a previous video I remember hearing you wanted to test water meth injection into the blower. Was this a typo in this particular chart, or? I can't imagine charge temps ever reaching that high while spraying water methanol, unless your weren't spraying enough.
IT WAS JUST A TITLE FOR A DYNO RUN WE WERE PLANNING ON TESTING-IT NEVER HAPPENED
@@richardholdener1727 gotcha. Well, do the water meth test lol. I've heard these M90s do great with pre-blower spray.
@@boosted0079 He wants to. The test mule spit out a rod bearing.
@@alantrimble2881 I seen that. Unfortunately, I've seen a lot of these 3800s spin rod and main bearings over the years. It's hit and miss with them
You got to get here quick when the vid drops if you wanna be #1.
Why not run f-body headers??
Could you run LS rockers on the 3800? If I’m right the LS has a better ratio like 1.6 rather than 1.5
Howdy Richard. Not supercharged, or turboed. What extreme cam upgrade would you recommend? Thanks!
lots of mild shelf cams avail
@richardholdener1727 thank you Richard, really appreciate it! Luv your show!!!
One of these in a chevette would be fun
So am I good with my setup or should I drop pulley size on my 3800sc intercooled with zzp xp hot cam. Stock heads, 130 springs, ls7 lifters, on a 3.4 pulley the car feels great but wondering if it's a huge difference to goto a 3.2 pulley or am I staying in a good curve at 3. 4 pulley
add e85 and boost
I would kind of like a little more data from this test. Even if its just lambda and bsfc i can figure the airflow and find out where on the compressor flow map it might be. This is really close to where the blower is rated to spin and with the 100hp pirate riding the belt on the front of the engine it makes me wonder how good the m90g5 is. Like, they suck a lot and leak like crazy and need too much power to turn but 380hp is still 380hp even if it appears to be above the rated flow capacity of the blower.
I DON'T HAVE AIRFLOW DATA OR BSFC AND OBVIOUSLY ITS NOT ABOVE THE RATED FLOW OF THE 3800 WITH THIS PULLEY
@@richardholdener1727 its right at the edge. The factory bottom pulley is 6.96(?) and with a 3.2 blower pulley and 6400 rpm the blower is at 13,920 rpm. I cant find a flow chart that shows this blower rated to go over 13,500. Its not so obvious. I cant find what the efficiency of this blower is at this blower speed and pressure ratio. Eaton never tested it. Do you have injector PW and Lambda? I cant find a source that says these blowers are rated above 14k rpm. The bearing in the nose is rated at 20k. The engine itself isnt rated to go to 6400rpm. I dont know what the maximum m3/h that these blowers will move is.
At what point do you need to machine the valve guides for extra lift?
GOOD POINT-I NEVER CHECKED
@@richardholdener1727 I heard it was around the 500 lift mark, currently building my engine and trying to figure it out
We've typically been advised that ~.540 requires that, since you can run an XP cam with shaved retainers, but beyond that the seals will get smushed.
Richard, lets hope that you are going to swap the supercharger for your usual GT45 turbocharger.
Let's hope he ports everything first. See wuts the most he can get with the supercharger
Is 210 a bunch of duration on an engine that size? Big gains
VERY MILD
210 degrees is a good street/truck cam. All the bottom and mid range torque fer ya.
Cams are decides by builder by engine components such as intake Manifold
@@jarredsmith8091 Cams should be picked based on where you want to make power. Regardless of engine build an 8.5-1 engine and a 12.5-1 engine of the same displacement will make power in a similar power band with the same cam. Same goes for cylinder heads. Anyone thats got real life experience or has watched many of richards videos knows that.
@@johndelta00 where u want to make power is based on the intake Manifold you use lol so
Omg! I... I.. just dont know what to say!!? - back to drooling!.
Any chance you could try a set of 1.9 rockers with this cam?
I don't have any
😆 I have jaws on the TV but I open my phone to richard with that shirt
Excited for the water meth testing
Why not do some new bearings and rings, with a dinglebary hone, to a good junkyard motor.
What pound rating valve springs did you use?
we used stock ls3 springs
@richardholdener1727 thank you sir! Appreciate muchly...
Will any of work on an 4.3
! Hey are there any high twist helix rotor packs to install into these M90 blowers? Do you know what I mean?
I DNO'T KNOW OF ANY TVS M90 UPGRADES
That combo would have been nice in my Buick ultra. Or my Grand Prix. Too bad it didn’t holdup
... Or an FBody Camaro.
Hey I got a question
