I need some help with cam selection for a carbed LS1.

I have a 98 TA with a stock long block LS1, Victor Jr, 825 mighty demon, rmvb th350. I have two different converters (3500 or 4800) and haven't decided which to go with. Anyway, this is a 100% racecar with ZERO street use. Everything that is not needed on this car has been removed so it is about as light as you can get one without cutting anything off the car.

What would be a good cam for this setup if I leave it NA and what would be a good cam for a small nitrous setup.

 

i have a magic stick 3 cam in my carbed ls1 and its friggin scary to drive now. pulls so damn hard in the upper rpm range.

i had really good luck with a jetted down holley 750 hp street carb. it seems to like the 70/80 jet combo, 5.5 power valve, and 30cc pump.

 

I have heard the MS3 worked good with a carb. Have you run yours yet?


The main reason for going with the carb setup is because we bought the car with no engine harness or anything so I thought it would be easier to get it going.

 

no not yet. i have a busted 3rd gear in my t56. but the 4.11s in my 9'' sure make 1-2 shift fun.

im running a victor jr intake, texas speed cnc stage 1 ls6 heads, ms3 with a 113las, and a hp street holley.

timing is set at 15* from 0-1000 rpm then its a steady ramp up to 29* at 3000 rpm.

it friggin screams man. It also helped i did some tuning with my fast dual sensor wide band.

 

Yea I'll have my wide band on there too when I get it ready to start. I was under the impression that a carbed LS needs a cam with a much smaller lsa than that but it sounds like yours is working out good. I have a G3x2 with a 112 in mine right now so I guess I'll give it a shot before I buy another cam

 

I ran my cam when my setup was carbed and it ran great! 236/236 .651/.651 110+4 lsa
