Did a search for carbed L92 setups and didn't get any results yet. Debating on what cam to run and looking to see how well these setups do at the strip. It'll be a low mile LQ4 and stock L92 heads. vic jr or gmpp? Anyone running a cam spec'd for a carb and are happy with it?

Check DMMizzell here and there's your answer. There's another member if I'm not mistaken but can't recall his user name. I'm going to run that combo as well with a GMPP single plane but was told to use a tappered spacer as tall as possible to add volume. Maybe the Super Vic doesn't need one. I have a custom cam, but was sworn to secrecy to not divulge the specs. It's a HR from Bret Bauer Racing.

Just remember that the L92 heads in stock form flow a lot in the intake side and not as much on the exhaust and with a carb/ single plane you need a cam with a tight LSA.

Well dmmizell's car is a lot lighter and he flycut his pistons, not sure if anyone local can do that for me with the shortblock assembled or not.

I already have a set of L92 heads brand new along with a pullout 6.0L with 55k miles on it that I bought last spring and has been sitting in my garage all year. This was a spare in case something popped up with the carbed ls1 in my camaro. Now I'm planning on selling off the ls1 and tossing this in, wasn't sure on a good carb designed cam spec or who sells the tools to flycut if I run a bigger cam. Local 4th gen shops don't do flycutting it seems.

A company called Lindy sells the tool.

i have th ls376/515 engine from pace. the cam is a 226in and 236ex with a .525 lift for both. it has propelled my 3422pd cutlass to 10.88 at 121 so far . idles at 7-800 rpm and pulls great to 6700

sounds like it runs pretty good 87olds, I was looking to go a little bigger on the cam if needed, what is your converter/gear/slick size and what carb/timing are you running?

I am running a LS3 with a Carb. 418 inches with AFR heads

The Cam I have is from TS&P 112 LSA 240/244 low 600's in lift in/ex
3500 stall and 3.36 gears.

No times yet on the motor but it PULLS way better than my old LS1 346

87olds442

the convertor is a 10inch ptc unit on the transbreak. with no limiter it goes to 53-5400rpms. on that pass i had the 2-step set at 3500. the gear is a 4.10's . i am running double adjustable uppers and southside lowers. with the pinion angle set at 3.5 degrees. the carb is a old school barry grant silver claw(750) and as far as the timing i run the 6ls2 (6012) box and i was using the("curve 3") timing chip in it.if you got any more questions dont hesitate to ask **** and that pass was made WITHOUT nitrous.

that's a pretty decent sized converter there, sounds like it's moving out rather well.

87olds442

its pretty good i drive it to and from the track.. on the highway its very good. i just cant wait to get back to the track and tyr leaving around 4500 or a lil higher then see what it does on spray

Just to confirm.
So you have a 5500 stall 10 inch converter on a Brake? and you can drive it back and forth to the Track? Wow... not putting a lot of heat into it? Your 60ft must be amazing... 1.5 maybe? You have video?

I am running the 3 chip in my ls3 right now. I am busting up at 5,000 RPM. My buddy thinks I need to come down on my rear jets?

87olds442

yeah i was surprised too when i put it on the brake and seen it go that high with the way it drives . the as far as the heat i have the big b&m trans cooler with the fan and is very good. on the highway with the 410's i am cruising around 3000-3200 and im doing about 50-55. so far my 60ft has been 1.47 leaving at 3500 and using a drag radial with 13 pds of air. as far as a video the only one i have is when i first put the car together and it went 11.27 first pass down the track. and with 5year old bfg drag radials. check charlieyls3 gbody on youtube. in my 750 barry grant i am running 81 jets with a powervalve and i believe 90 in the rear . on 10.88pass a/f was right at 13.5. i think if i put a lilmore into it and got it to around 12.5 it would have went better
