Ive got a 1990 camaro 305 tbi. I'm switching over to carb and a few other goodies. I'm wondering how much HP will my new combinations make? Here is the list.

Heads from a 91 gta that have been ported and have new comp springs

Edelbrock torker 2 intake manifold

Holly 600 4bbl carb

14in holly filter case with k&n filter

3.42 posi rear.

 

Will you be changing out the cam and why a Torker 2 intake? I would go with the performer or performer RPM air gap intake.

 

Not changing the cam just yet. When I do I will be going with the lt1 cam, I've heard good things about those. I went with the torker because I heard itd give better performance when mashing the gas. Would the performer have been better? This is all going on to my stock lo3 motor

 

What heads are they? If they are off a 350 you will likely lose performance due to the compression drop.. I'd suggest returning that intake or selling it and getting a performer or performer rpm, that intake is a huge mismatch, especially when combined with your stock cam. With the above configuration expect performance to be worse than stock.

 

Torker II is terrible, you won't like it, especially on a 'small' motor like a 305.

With a 600cfm Holley, the best intake for you would be either a Weiand 8120 or Edelbrock Performer EPS. They are designed for use with tamer combinations like the one you have (fairly mild cam, smaller cubic inches) with a squarebore style carb like your Holley. They also will not have hood clearance issues, as they are only a little taller than your TBI intake was, but being modern designs, will produce a noticeable amount more power and torque.
