I can see why big dollar engine builders know who Richard Holdener is. You produce excellent content that is relevant to novice guys and build more interest which leads to them eventually. Great vid as always
Richards tests are valuable info for everybody, even if only to reinforce what you know.
He deserves way more than 270k subscribers
I really appreciate that you spend time with both oddball engines and popular ones. True gearheads have a wide bandwidth of interest and are not brand loyal boo birds. I love all kinds of different engines from model T Fords to Hondas, and LS's , too!! All of these things are really fun to play with and learn about. The rec port 6.0 LS in my 53 year old Land Rover just went "Clunk", now I'm learning about how I can build a stroker out of what's left HaHa!!
Majestic. Rewatched at least 5 times. Next we need to see 250 + intake cam. 12.5 compression. And test ethanol vs methanol. 600 hp would be magnificent
cams like that won't fit
Been watching your vids for a while now and you never disappoint... im building a gen 3 6.0 for my camaro and your vids have really helped me with what path i wanna go with her! Ty for the vids keep up the great work!
I appreciate that!
@richardholdener1727 great video. I've been waiting on some more high rpm testing. Any high rpm 416 ls stroker testing?
@richardholdener1727 i didnt think these heads would work with a 5.3. I have been looking for something better than the 706's on my rcsb silverado. Its a street strip truck. 4l80e swapped 4k ptc converter, 4.56 gears, tru trac posi, 1 7/8 LT headers, btr stage 3 truck cam but swapping it to a btr red hot cam and using nitrous outlet x series single fogger nozzle for no more than a 200 shot. My lm7 5.3 is stock bore space 3.780 with dish pistons. Would you say that these 220 fast as cast heads with .030 milled off and a .041 mls gasket and the btr redhot cam work great together?
A tighter LSA does work. Richard, you proved this yourself 2 years ago with testing. The whole, it’s just a result of duration inputs is wrong. In short, Mr Vissard is correct and Mr Tooley is not. Awesome video!
anyone that says you need a tighter lsa as a general statement doesn't understand cam timing. Do you know what the valve events are right now?
I'd like to see a David Vizard spec'd cam for this combination. He seems to be a fairly sharp ole fella , I'd like to see his theory in action in a back to back test. Thanks for all you do Richard, keep up great work. It is truly valuable.
Agreed!
BT would be offended if DV’s specs made more avg power. BTR throws Rich a lot of bones! BT & DV have opposing views on cam specs, specifically LSA’s. DV says they are key and BT says they mean nothing! The videos are out there saying so....
@@trailerparkcryptoking5213 my money would be on DV.
any time DV wants to spec an LS cam for a test or shoot out with BTR-I'm ready to test
DV is clueless. His theory calls for a cam that is wildly wrong.
Love your videos, makes the process a lot easier to understand
Love the data and value your videos offer!
Awesome work. I certainly expect it will make 1620HP with turbos. Can't wait
Long live the 5.3!!
M1 of course!!! It will push some nice numbers and give it a good cleaning! Lol. Just remember to run some regular through it afterwards and toss the oil.
I really like your testing, you have the best LS information on UA-cam. How about testing exhaust, header diameter and exhaust diameter. example 1-7/8 header with 2-1/2 exhaust vs 1-3/4 headers with 2-1/2 exhaust. you could also include 3" exhaust. this would be really helpful for us daily driven guys.
header tests are up
He got lucky with that l33 that motor been running great and his been working the heck out of it 😮🎉
7000rpm+ always sounds good 👍
Nice looking tq curve.
Nice job. From what I've heard e85 doesn't make a big difference in a N/A engine. But let's see ! Inquiring minds wanta know !
Now this is what I’ve been wanting to see someone do for a long damn time
Any day you break 100 hp per liter is a good day. BTW, thanks for the closeup shots of the hardware. 👍
I'd love to see this exact setup on e50, then e85, then m1, each tuned for max timing.
I'm ready to see all of it !! I've got a l33 sitting around and I've been thinking about putting it in my kurtis v drive. Interested in what this little thing is capable of.
Seems like a good candidate for a big bang 😉
That thing is gonna need a huge converter. Definitely shouldn’t run this setup in a 4dr truck, but it’ll be nasty in a single cab short bed.
I run a 212/218 truck cam to 7800 with a turbo. It would be pointless NA but with the turbo I make great low end power with the baby cam and carry it waaaaay out
@@bthllp5.3l too?
Nicely done! I am hoping for (only) ~390/~390 out of my street L33... BTR Truck Torque cam FTW
Awesome video, after this it just makes me wonder can you get the junkyard 5.3 to 600hp N/A?
So on 6.0, with similar mods, we could see 600hp, maybe even more with rec port heads? I would love to see this same setup on a 6.0, reving to the moon. As always love the videos, great info and nothing beats the sound of a screaming LS.
Great results, I'm curious about another set of injectors for nitro and single injector options for meth, water, amonia and others. What about propane injection also ? The bottom end should last under 8k for quite a while the rod/bore ratio is a screamer. I would guess you could find another 100 hp on the above suggestions, especially Nitro.
Would love to see a m1 setup for comparison. E85 would be cool aswell, love the content as always! 🤘🏻
Richard! You be hyped! 😹
Hell yeah this is the stuff I like, I would like to know more details like what lifters springs and valves it has
stock lifters (junkyard), BTR Ultimate RPM springs, valves are stainless
A well seasoned 5 3!
I would like to see an overlay with the previous configuration. Also I would like to see some testing with Texas speed CNC ported 243/799 heads. I want to build and swap a 6.0 into my 1973 Nova, but the numbers you are getting with a more readily available 5.3 has me reconsidering that idea.
you should do a 6.0L
Some day it may pull a piston pin boss apart. But hey- until then its nuthin but glorious.
I'm curious what the overlay of the 510 hp combination would have looked like vs. this combo. And... I wonder what just changing the camshaft would have done for power and leave the LSXR on it.
comparison coming next
I’d like to see this combo with the fast manifold back on it. I think it may lose a couple hp up top but make that up in average tq.
That is awesome
Turbo with water injection on pump gas please.
6:29 😂😂😂 Cars & clothes, that’s all, all my patnas know.
Small bore mast rectangle port heads, solid roller cam, tunnel ram intake lol
Put the factory heads back on and see what u can do w a factory long block!
I buzz 7800 with the ms3 cam and twins for awhile now. 706 heads w pushrods and springs and twin 78s. Seems fine def slowed down w less rpm at the shift.
Tick has some nice cams for lt1 isky has the new old man’s garage roller cam and the gm hot cams cam
Valve train upgrade, E 85, and dry sump.
How does the BTR intake compare to the FAST w/short runners?
Also, what about increased CR and a camshaft with a wider lobe separation?
And would you have less mass and greater valvetrain stability with conical springs?
I like the new swipe edits
fancy
That’s awesome.
Valves & lifters. Spin it to the Moon

On one of the episodes of engine masters, they were trying different size heads on I believe a 408
They showed that the 225 head was too large for that motor
So if a 225 is too large for a 408, wouldn't it be too large for a 325?
Wouldn't a 195 be maximum?
Guys on engine masters even got great results with the 165 heads. They actually impressed themselves, brulee even said that he would take the small head and cam. Com combination for a daily driver
a 225 head is not too big for a 408
Try different collector 4-1 pipe size smaller and bigger beginings for exhaust pipe
I was going to do a destroker, but I decided against it since I'm not keeping the car. But im keeping my 4.8 crank for my next 6.0 ls car. Want to get like ~8.5k rpm.
Gonna slowly collect parts like an aluminum 6.0 block, flat top pistons, etc. Want an American version of the bmw s65 engine.
you don't need a short crank to run rpm
@@richardholdener1727 misspoke, short crank because my trans won't fit and I can't find anyone to machine it shorter .
SAA-WEEEET 5.3 😮😊❤❤❤
I would love to see this combination with Boost
It would make a lot of pulls even at that rpm. Also wouldn’t a tighter lsa make more low end and lose top end?
All the old sbc guys were happy with 1 hp per ci. Taking stock junkyard stuff now days and getting 100 hp per liter is no joke. My 6.0 is making about that n/a and it’s a wild ride For stock junk.
Hey I want to see some gen 2 lt1 camshaft stuff 😊
Some rumble uploads would be great!
I would like to see it on E85 then M1 ,M5 see how that 600 ganna be easy
Load it up at lower RPM to see what the torque is doing and figure out what it would take to keep it alive with a 8000rpm redline.
E85 and a 15-1 compression ratio.
TR-1 Nice. Short runners hurt the torque a bit, would be good to see if it claws back any with the Red Hot.
BTR boys like their big duration splits on their cams.
60cc chambers, e85, and compare the trinity to the ebay/Amazon sheet metal intake. Any windage issues at that rpm? A vacuum on the pan would probably add some hp.
E85 fuel would be a great idea for the street car guys.
With that high of an RPM range this setup ought to be real good with a big nitrous shot.
id love to see the numbers with that cam and intake on a ly6
I wana see a set of small bore mast square port heads tested on a 5.3 with a stroker crank
nice!!. I have an LQ4 with forged rods and flat top pistons with a trucknorris cam. is it possible to see what a bone stock LQ4 can do with just a btr truck norris cam swap. im curious about what hp I making. love your vids!!
you are stock plus 50 hp
What is the rev limits of a LS / 5.3 engine? 7700 seems like a lot of rpms 🤔
540 hp out of a 327 CID NA engine that lasts. Great time to be a hot rodder. This would be a fun engine in a street car with a manual transmission and aggressive exhaust sound, let it sing.
@Richard Holdener Keep turning it higher and higher until it blows but tune her right so it doesn't prematurely blow. This could be interesting for the future na builders trying to get into budget na builds by reving to moon with a say 6.20 or lower gear🤔
Current set up, no point in turning more rpm. Power leveled off at 7500
@@jacobjwilson92in drag racing you shift gears after HP starts to fall off. Hold on to your torque multiplayer longer....
Do a junk yard 2jz- ge to a Na build. All dyno runs from stock to fully built. Then incorporate to a Gte.
would be cool
I'd now like to see the same combination on the 4.8 to see if you could break 500 with it. Could be interesting considering the tectalk We had a wile back.
@Richard Holdener - I vote for this one next!
Do a 4.8 next
I do have one
Hi Richard, congratulations on the test,i was wondering how much more horsepower this exact test would make if you were to bore it 30 over?
that only adds 3-4 inches
Yep, this is the recipe I'm gonna follow for a build I have going. E46 M3 party car. Here's my question - the heads you mention are hand ported. Can BTR provide similar heads for purchase or what heads would you suggest to get really close to these units? Any chance you could run this package with a carb manifold?
talk to btr about the porting-but you likely don't need it
More cubes would be fun. How about boring the block to 5.7 to see if it's worth it ? Run it in the exact same configuration, we know it will make more power but how much ? I do have a Gen 4 4.8 and a couple Gen 3 5.3's sitting around with a set of low mileage Gen 4 5.7 pistons sitting under my bench. Is the cost of boring, rings and gaskets worth the 40 (?) extra hp ? Inquiring minds would like to know. Thanks for the video's.
IT'S MORE LIKE 25 HP
👍👍
Measure and try to eliminate blow by. Diamond hone cylinder walls straight, Will nascar .5mm rings, tighter piston clearance work on the street.
no need for that on the street
This is so badass! Man i love Chevrolets! I would love to see it stay N/A but do a high compression on M1 or different race gas with a carb on top for simplicity!🇺🇲🇺🇲🇺🇲💪💪💪
Lets see a 5 minute 7700 rpm hold at full song. :-) Test that cooling system out. 🙂
I saw the heads were milled, but I didn’t catch the compression ratio?
YOU NEED A TIGHTER LSA IN THERE IT WILL MAKE A LOT MORE POWER, there I said it.
Mill the heads .090 with some thinner headgaskets. She'll thump then.
Told ya the cam and intake should match🤪. The long runner intakes aren't meant for 225+ duration cams. Especially when trying to tune them on the stock ecu.
Lots of guys run sbe past 8k rpm.
And ofcourse good fuel test would be great.
the 225 cam and FAST intake comment is just silly
For shits and giggles do a comparison between the doorman truck intake and the tbss intake eventhough the throttle body opening is two different sizes but still would be interesting
I tested the Doorman truck-it was not good
Would you gain much power by putting a good set of rockers on it?
Rich can you do a video on the dodge,ford v-10 n/a and boooost!!!!
maybe the Ford
Curious what a 5.3 would make with high compression on some good fuel.
@Richard Holdener as one your tighter LSA people… you mentioned the heads were shaved but didn’t say what the new CR is? Crunching the numbers comes to a 110 LSA if the CR is at 10.5:1 but… that not gonna help peak power.
WHAT ARE THE VALVE EVENTS AT YOUR MAGICAL 110 LSA? COMPRESSION MIGHT BE LESS THAN 10.5
Mr. Holdener, will you divulge the part number of the cam featured in this most exciting combination. after watching this video i would like to try this in my forged setup lm7 5.3l sbe. I, am going to hit them up for one of there cam kits with springs retainers etc.
I provided the cam specs and name (from BTR) in the vid
I think we should change nothing but a trunnion upgrade, and start squeaking up the compression ratio somewhere in the 13s andE85. Bring that torque up. I do think that there is the potential that we’ve reached the max CFM of those heads. At the higher rpm range I’m wondering if we’re getting some nasty low pressure zones in the transition from the square openings to the Cathedral port. I guess what I’m saying is if we went straight to a rectangular port from a ported cathedral port, we would probably see some higher average power output.
Guys say those bushings aren't as good as a bearing... Very intriguing though
the heads flow enough to support 650 hp
Nitro/m1 mix and a super thin head gasket. I bet you will make 800n/a
Great looking piece, how much power is lost when that aluminum heat soaks?
myth
Thanks, I've always wondered that with my old 402 with the aluminum intake.@@richardholdener1727
Id like to see this setup vs aftermarket heads. How much more power will they offer over stock ported heads.
professionally ported stock heads can make this-see the big head test video
I'd be curious to see what may be hiding in a little fine tuning....just to find out how the thing is doing across the rpms....and if there is anything more there!
fine tuning?
wonder what kinda torque converter this would need. 4k? 5k?
I'd like to see it at 12/1 on E85
Stock rocker arm with trunnion upgrade???? Awesome vids as usual. Thank you
stock rocker arm-no upgrade
Wow. I’m totally shocked by this. Another myth busted by your tests. Thank you so very much!!!
a tighter LSA does work better on a short runner intake as the overlap draws air better on the short runner
no
I think you should stroke it, or at least bore it over. I’d like to see that torque pick up a little down low, I think it would make it more Drive-able and less racing specific.
E85 on lmg and flex fuel os
E85 FOR SURE!!! and why not do M1 while you're at it. Don't forget to include "the tune".
Tighter LSA 😅🎉🎉🎉🎉
Do that same combination on the 4.8 /6.0 and see what the difference is and is there a big difference
see the stock 4.8l vs 6.0l video
Hi Richard ,just looking at this combo would these specs be just as great on a 5.7 ls1 with 862 ported heads with 1.95 valves also running 12 to 1 comp or would going up in cam size be even more beneficial?
if you have enough p-v, more cam will make more power
What was the idle speed and vacuum?
I’d like to see the power difference, with some short travel lifters, another cam change, and 9k+ rpm!
Now that's seems real interesting 🤔
we don't have enough p-v to run a 9000 rpm cam
@@richardholdener1727 so it is safe to assume that things start to stretch at that rpm, that's why you would have to worry about piston to valve clearance?
Why don’t you try the tighter LSA cam and see if it makes more power
