Thread: sb 350, is 900hp with forced induction possible

Tweet

Ive never heard of "Iron" pistons.... I think you mean forged aluminums like Arias, or Lunati.

As for running 10's, Hp and Tq are only one part of the equation, the other is TRACTION, here's an exampe.
I have 2 buddies with really sick street-driven cars..

One is a 1969 Camaro, similar to yours except dark green. He's running a full built 468 LS-7 pushing 613 WHP on a chassis dyno.
This car *should* run 10's given the light weight of the body.....But he can't because all it does is spin like crazy, drag leaf springs and traction bars don't cut it, neither does the 9" slick he can fit in his stock wheel wells.

Another has a tubbed out '71 Camaro, running an "as is" GM crate 502 rated at a mere 500HP at the crank. He gets good traction as you would guess, and clicks off 10.40's all day.


So, add in ladder bars to your cost, as well as a full drag suspension set-up.

Another thing is that to get 900hp on a SBC, turbo's will be easier then SC.... And turbo's dont run cheap.... I'm afraid to even calculate the cost.

Nothing you have now will be of any use, so here's a few items you can START pricing;

- Stock GM small-blocks have been known to crack at high Hp levels when driven more than 2 minutes a day, so you'll need a Dart or better block.

- Forced induction NEEDS fuel injection if you want any control or power, so your intake/carb is of no use.

- No amount of porting will give vortech heads the necessary flow to support 900hp, you'll probably need 18 degree or better.

- Forged aftermarket crank, forged H-beam rods, GOOD forged pistons (not low-end TRW's), metal head gaskets.

- Crank girdle, high strength fasteners, dry-sump anyone?

Transmission? Differential? Tuning? Roll cage?

Notice we haven't even started adding the turbo's, intercooler, BOV's, wastegate, exhaust, fuel pump, fuel system, etc..


Its very easy to throw out Hp numbers, but actually getting them is another story. Set a REALISTIC goal, try for 500hp which is enough of a challenge (and expense) out of a small-block - and if you have traction and tuning, is enough to get you in the 10's.
