thinking about building a new motor for my car, ive been away from fbodys for a few years, if some one was wanting to keep the tpi is 400-450 HP supercharged dailey driven possible? I got the tranny built allready with allt he clutch upgrades, beast sun shell and billet plantery, and a 2400 converter. Thanks Joe

 

id like to have a mid 12's street/autocross car my last iroc i used nos, this time i dont want too

 

build a badass 383 for some killer low end torque. it should perform great on the autoX track since all the power will be at a nice low rpm...very useable.

to run decent power with a SC you'll have to (or want to) put some stronger internals in the motor anyway...so why not just build a good torquey 383 and forget the extra $5K for the SC.

 

You won't need 450 hp to run mid 12's in a thirdgen. More like 350.

RWHP right? I doubt that it is feasable with crank hp.

 

Depends, some guys make like 315rwhp/360rwtq and run mid 12s with the right tire and gears, and maybe even some weight reduction. That would be about 355hp/415tq.

 

I am a fat kid so ill need the ponies

 

450 hp with MAF and you'll start to run into some drivability issuses in your tune,

might want to consider map, or even better for boost a computer from a turbo sonoma, can't remember the model off hand

 

I know back in the day, magazines were bolting on Paxtons and getting good results.........not sure of the actual HP numbers, but some impressive gains to be sure.
