408 build thread 98 ss
I don't even have engine/transmission yet lol. All I've done so far is pull the stock engine/tranny and sell it. Still saving for the 408 and then I will buy tranny. What is your 403 in? And what weight? I ran a 12.3 with a full weight bolt-on ls1 engine with stock cam/ **** heads and a little 3200 stall. So I'm really thinking a 408 with big cam, better heads and a bigger stall should do 10's..

Thank you! That's what I'm hoping for! It's in an 86 cutlass 442 so it's a pretty light car. The aluminum block should lighten it up even more. Doesn't have ac and it has billet street lites for wheels. Running a 275/60/15 right now for tire and it has the stock 8.5" 10 bolt with 3.73s
senicalj4579 ran 10.9x with a h/c/i SBE with no suspension work at all, 10 bolt, and ss3600 stall, and he drives it 2+ hours to the track, so with a good launch I think you will run in the 10s with that setup. Op, are you going to run the heads stock or have them ported/milled at all?

So here is the plan
ENGINE:
TMS 408/L92 heads
23x/24x .60x .60x cam
Ls3 intake/90mm TB
FTRA setup
TRANSMISSION:
LVL 5-6 rpm 4l60e
Circle D 4200 Triple disc stall
OTHER:
Weld Rts wheels
Skinny fronts/28" rear
No A/C
No spare.
I'm thinking this should be a solid 10 second car what about you? Will run N/A for quite a while and then plan to hit it with a 100 shot or so.
Another big goal of mine is to also pull the wheels. Any reason I shouldn't be able to do that with this setup N/A?

A guy to a dremel and pliers to the baffle and it fit fine afterwards.
