I wanted to know how much power u guys think i have, and what i would do in the quarter.

85 Z28
350 carbed...holley 600cfmVS...holley street dominator intake...performer cam, like a 440 or something lift...3inch catback...shorty headers...K&N open element...no A/C...no radio...700r4 with aftermarket cooler and deep pan...electric fuel pump...carquest shocks...16inch stock wheels...Mallory HEI distributor...most of this stuff is brand new, tell me what u think...

 

oh yea and a posi...dont know what gear i have though

 

At the rear anywhere from 250-290hp

 

with junk stock heads, and the junk performer cam, you'll be lucky to run solid 14's if you're at altitude, maybe mid 14's at see level. Not to sound rude....but that performer cam SUCKS. Unless you are talking about the performer RPM, then its slightly better, but not really. I'd say at the rear you'd be right around 230 until you upgrade the heads/cam, no matter what else you do to the motor besides nitrous/blower.

 

yea i know it sucks....it came with the car, and i deeply depsise it, i want like a comp with a 480 lift on exhaust and intake, with all the pushrods, lifters, roller rockers, and springs and stuff....i dont know about the heads tho, i want to get some new heads but my budget allows nothing.....what do u think when i do the cam kit switch

 

I would definitely go with some Vortec heads, they aren't too expensive, you could probably get a used set for around $350-$450. Not too bad, i don't guess.

 

If you are planning on switching the cam and heads....and you want a PROVEN combo....do this:

Comp Cams Extreme Energy 274~ $99
PAW SBC lifters ~ $30
Vortec heads ~ $399
Comp Conical Valve springs ~ $69
Buy the special tool to mill down the guide for standard valve seals ~$20ish?

With this combo you would make over 400HP easy at the crank. Chevy High Performance built an engine like this with the same cam, roller rockers, and a really mild port job on the vortec heads and made 440HP, if memory serves correct. With that much power you could run 12's easy if you setup the car right. That is the exact same combo my firebird had before I put in the new motor, and I got a 12.6 out of it at 3,200 feet elevation.


EDIT: OOPS!! By the way...this is ChrisFormula355 NOT 5siz!!! He forgot to log out when he used my computer!! HAHAHAHAH

 

thanks chris, i will definitely look into that, as i want vortec heads anyway
