88 notch

I was thinking about buying a short block from CHP. I was thinking of the 306 with the forged rods. I was wondering what the combustion chamber size on my heads are, I have gt40's from a 94 or 95 Cobra. I was also wondering what horsepower to expect and what kind of times I might be running. I have a Cand L mass air, CAI, 70mm throttle body, Edelbrock Performer RPM intake, 24# injectors, 1.7 roller rockers,and was thinking of an e303 cam. If there is a better cam for my combo, I am open to suggestions. I have a five speed and was going to put 355's or 373's in the rear. It is an 88 notchback
