hey everyone, i'm new to the forum's and really new to the "muscle" car scene. i built a tuner a few years back and now want something new. i plan on dropping a 400 SB in an 83 camaro. i had a few questions about the 400.

It is a SB 400 4 bolt main. standard bore. the motor has a 350 horse RV cam in it. the guy told me that it has 350 sb heads steam drilled. also the tranny i will be going with is a 350 turbo with a shift kit?

ok so my first question is what does everyone think of that setup so far???

i want to really build a quick/cheap car i can take to the stip. i want to be in the 11 second range, and dosn't have to be all motor but would prefer it to be.

so my next question is what would everyone change/add to get the 400 to run 11's all day at the track??

 

There's no useful information to comment on the setup. "SB 350 heads" and "350 horse RV" cam are meaningless.

 

The heads and the cam.

 

Vortec heads and a cam could get you into the 11's with with nitrous.

 

I got a friend's 90 firebird with a 400 sbc into the 12s on the motor with ported L98 heads and a big cam. It was the dreaded Performer RPM grind that sofakingdom hates... with a 750 Carter AFB and 1 3/4 SLP headers (expensive) at first until we monkeyed with the TBI in a few big ways.

Getting into the 11s from there I would guess would mean deep gears (4.56? probably) and bigger cam with better heads. I'm not sure vortecs could get you there. I think they probably run out of potential on a 400 before you hit the 11s.

 

I run vortecs on my car. I've ran a 12.8 @ 108 so far. I've yet to get a good launch down as my 60' is still 1.887. I know if I ran roller rockers and an electric water pump and 3.73s in the rear I could go lower 12s. On nitrous I would imagine you could go 11's no problem.

The build I went off of made 430hp and 525ftlbs of torque. With a light enough car you could easily go 11's.

A buddy of mine said one of his friends ran 11.7 on a vortec headed 400. He's a real trustworthy guy, but in this game, I don't believe it till I see it. But it's definitely possible.
