What was the stock horsepower for an 82 gmc 350? I just installed an edelbrock performer plus cam, performer intake, and a 600cfm performer carb. Also, my heads were shot so i had to work with what I have and threw on a set of 305 heads with 1.84 I and 1.5 E valves. I did a compression test and I have between 160 and 175 psi. Is this way too high? What would be my new horsepower approx.?
Thanks for the help! ![]()
