GOOD JOB BROTHER!!!!! Way better than paying a grand or more for a Holley intake with the MSD box. Getting the tune right be the hardest part. That's cool!!!!
Great thing is the tune is really simple, it’s mostly just turning off unneeded parameters and other than the timing curve there is nothing to tune. All fuel tuning is with the carb, so a cammed engine would be very easy to tune for a beginner.
@TheAdrian7826 This gentlemen comes up with ways around the norm and can potentially save people dumb amounts of money. More people should be seeing his videos. I've been telling everyone about him and I figured out how to share a video.
Seems to run fine, but once in the car I will hook up the MAP sensor and adjust the spark table again. Right now it is like a distributor with no vacuum advance, works but can be better. Love the tri fives, I still have a few 55s that will be on the channel.
Current tune is very basic, all timing adders zeroed, timing retards zeroed other than the knock sensors. Timing table set linear 10 to 28 degrees all in by 2800. This works but will be better with a MAP sensor and a factory style timing table, will be a future video.
Thanks, it works, myself I am going to stay with fuel injection, but this would make cam tuning on the fuel side much easier once you have the base tune for the carb loaded in.
Great video to bad the cam bearing was the issue on the oil pressure. Just wondering if you reprogram the ECM for the public for a side job? Thank you for your wisdom.
Before you tear the oil pan off, check the 'barbell oil galley plug located behind the rear cover on the drivers side of the engine. May be stuck or have a damaged o ring.
The advantage of the MSD is being able to make changes on the laptop without HP Tuners. There was at one time a circuit board that converted ECU's to work that way. I like being able to make changes on the fly
What would you change in the tune on the fly? Tune is pretty much nothing but the spark table. All the fuel changes will of course be done at the carb. Tune can be done for free on a laptop with LS Droid and Tunerpro, no need for HP tuners.
Can you add timing at light load, much like a vacuum advance on a distributor ? MSD has that feature and it makes for a huge difference in economy and response at light loads.
sure, you could wire in a map sensor and adjust the timing table for manifold pressure, the option is there. This is new to me, so I am going to try it this way first and then go from there.
It is a harness I bought from a private individual on ebay, same ones sold on ebay for $75 new. I go over the harness in one of my other videos, I am using a P01 PCM so this is a DBC harness.
This is exciting. I know you scored a deal on the $40 eBay harness but seems with this carb setup could a person easily strip down a stock harness? I know with the regular EBay harnesses you buy for the injected setups it’s a no brainer- but with how stripped down the harness will be now- would it be easy to redo a stock harness? Thanks for another great and informative video series!
Hey man can faulty TPS cause a "dead" (unresponsive)throthle pedal ? I got a p1516 code on my ls swap c1500...pedal was working just fine before i installed a mechanical oil pressure gauge. I took the throthle body off and noticed that I could hear like something is loose when I move it from side to side. Not sure if normal .(DBW)
So if you have a 4l60e on there...would not having a TPS sensor affect the shifting? I did your jy 4l60e harness repin and I think I put the TPS 5 volt reference pin in wrong spot. Car will upshift fine but not downshift when I step on gas and obd says low TPS voltage. Gotta wait til a little warmer to check it
No tps will affect shifting, and did you fix the white 3-2 downshift solenoid wire on the transmission plug? I covered it in the LS1 to vortec conversion video
@rust_hoarder_garage yes sir...I did that one. When I first fired car my aftermarket valve cover set up sucked about five ounces oil into intake in less than 10 min. 3 injectors were stuck and lucky it didn't hydraulic. Obd showed like 7 trans malfunctions. I didn't have plug in all the way. Tight fit but after that no more codes. I rolled passenger valve cover up and the drain holes for the pcv part were lined up perfectly with the pushrods. Went to junkyard and got some 02 valve covers, cleaned them up and drilled the extra drainhole . Had eBay 92 mm throttle body that whistled like a vacuum cleaner..TPS didn't work. So I got a 98 Camaro dbc and put it on...had to grind the steam tube almost flat because I have a speed master aluminum intake and it was hitting the water pump. Did an ICT billet type serpentine setup. Belt around the ls1 tensioner kept riding into the bracket. Bought a gm tensioner and fixed problem. Nice cnc was brand on eBay. Actually not bad set up. I did the summit racing 8718 roller cam with ls1 lifters. Sounds pretty healthy. Few more bugs to work out. I like all your info
@@rust_hoarder_garage I'll get it...I'm an old school muscle car guy. I rebuilt 5.3 for wife's 1980 z28. Bought tb as intake for it but truck intakes won't fit under hood so I bought the speed master. It's actually pretty nice intake...sits lower than ls1 but good rpm range. So if you decide you want the ss intake I have one. Was gonna smooth it out but havent
Very cool, I am also an old school muscle car guy, I built Camaros/novas/ Chevelles for years. Nova build will be coming up! Thanks for the offer on the intake, I have a couple TBSS intakes but haven’t used one yet.
I just grabbed the cheapest one on ebay that was listed for LS1, has to be for gen 3 to work with the cathedral ports. There are mulitple sellers on ebay with the same intake.
I have the spark table set for a linear curve across the RPM range, no timing add or retard tables are active other than the knock sensors. MAP sensor is disabled.
@ that’s terribly inefficient, the map sensor is like the vacuum advance on the distributor. Under load it needs to have less spark, granted, you can live off the knock sensors instead, but that seems not good.
Agreed for the street it is a good idea, but it is not a MUST have, a lot of guys run these engines with carb in race cars, demo derby cars, etc. I am going to try it this way first, that is the great thing about experimentation. Once it is in a vehicle, I will try it as is and then with MAP sensor and adjusted timing table.
Wow I learned something new today I was always told you needed a msd box to run a carb
No MSD needed, thanks for watching!
No MSD or Daytona Sensor is just easier to hook up plug in and play.
You the man , just needs a rebuilt
Thanks for watching 👍
Very interesting! I didn't think it would run that well with the stock pcm. Thanks for doing the test and making the video!
Seems to run nice, throttle response is right there. It should be even better once the MAP sensor is tied in.

@rust_hoarder_garage That is so awesome!!! You just saved alot of money for people!!
Outstanding Video,I have a 4.8 I want to put into a 69 C10 and I may just go with a carb,I take it you used HP tuners.
@TheAdrian7826 This gentlemen comes up with ways around the norm and can potentially save people dumb amounts of money. More people should be seeing his videos. I've been telling everyone about him and I figured out how to share a video.
You're a really nice,cool guy!! ❤ I Really Really Appreciate You For Sharing!!💪💯
No problem 😊
Do a video on depining the harness for a carb Ls without trans wires please
All you have to do is trace back the unused wires and remove them.
That’s sweet! I may do this for my 57 Chevy. Got a 5.3 with the truck intake but a carb and finned air cleaner would be cooler
Seems to run fine, but once in the car I will hook up the MAP sensor and adjust the spark table again. Right now it is like a distributor with no vacuum advance, works but can be better. Love the tri fives, I still have a few 55s that will be on the channel.
Can you demonstrate on video how you set up the tune?

@@rust_hoarder_garage thank you👊
This makes me want to go the carb way. Awesome video.

@@rust_hoarder_garage I look forward to the tuning video
Check out UA-cam videos on using LS Droid and tunerpro to see how to tune the gen 3 pcm for free, works great

No problem thanks for watching!
@@rust_hoarder_garage cool !! I love the idea of NOT USING A MSD BOX
Could the MAP sensor be used to build a vac/advance curve for street engines?
Yes it could, and I plan on trying that once the engine is in a vehicle.
Thats awesome to see work like that. Now wonder how it’ll respond in a vehicle
Thanks, should be the same as running a distributor with no vac advance, going to try it this way first and wire in a MAP sensor in the future.
@ you could still adjust timing with hp tuners also
Can you provide link to the 40 dollar harness please
It is a harness I bought from a private individual on ebay, same ones sold on ebay for $75 new. I go over the harness in one of my other videos, I am using a P01 PCM so this is a DBC harness.

You sure could strip down a stock harness, it would work fine!
@ what program are you using to program the computers? HP Tuners?
Did this one for free with LS droid and tunerpro.
That was awesome, I didn’t think it would run that smooth, I’m with your Friend, a carbed LS would be cool, thanks.
@@rust_hoarder_garage I’ll look into them! Thanks! I feel like I should pay you something for your knowledge!
if you did use a MAP sensor where at on the intake would you put it?
Vacuum line off the rear intake port to a remote MAP sensor like used on TBI engines.

Can't say, I have not had any DBW issues.
@rust_hoarder_garage oh, ok..hopefully when i change the TPS , it'll fix the my issue.
Brother, I would drop the pan and just look at the O-Ring. It may have the wrong one in it.
We will see!
@rust_hoarder_garage I am really curious. I hope it's the o-ring. That would be awesome!!!

I just grabbed the cheapest one on ebay that was listed for LS1, has to be for gen 3 to work with the cathedral ports. There are mulitple sellers on ebay with the same intake.
stuck relief valve or broken spring
We will find out soon!
Hopefully it is just an o-ring! FYI you do not need to run a cam sensor. One less connection required.
Even better! I will have to try it without the cam sensor, thanks for watching 👍
Thank you sir!
Thank you for watching!

Was there a tune need or just what?
Yes, as I said in the video I had to make a tune to do this, it is not plug and play.
Could you post your tune
Got a link for that $40 harnsess, or sellers name? thanks I'm new to LS but not old school chevy engines.
bought on ebay from a private seller, not the mfg, this video goes over it
