Right now my 81 camaro is stock I am installing headers, a edelbrock performer intake and edelbrock pefromer 600 car, and a 214\224 cam cant rember all the specs any estimates?

Taking for granted that there are a few miles on the motor, and these mods are a good match for your set up, I would guess about 150-180 to the ground.
(New they had about 140)
Just my .02
Good luck

Engine only has 40k on it, just looking for a little extra power until I can build a new engine.

throw a NOS cheater kit on it..

I thought about that but its a street car and I would never use it.

You should expect maybe 15-20 HP, not much more.

The biggest problem is your low CR IF it is down in the 8.5 CR. range????

Get it up to about 9.5 to 9.75 to 1 AND you will make more power with your combination!!!!

cam is a bit big isn't it? I would pick a smaller one that would build more torque to help the high gears I bet it has. Plus you won't want to spin it that hard. I would look at the 204 214 cam it would help save more cylinder pressure. Also on the cheap a stock 350 cam in a 305 makes a good cam.

I went a little bigger on the cam car is a 4spd with 3:90 gears about to be installed

The 350 motor's cam should be the great old -929 cam..

A Performer cam, (204/214), should do nicely too..

Just saw the 4-speed and future 3.90 gears!! 214/224 is a FINE cam!!
