Ok i just want to know if this is even feasible. I currently have a 77 302 with an Edelbrock intake, higher compression pistons (dont know what compression tho). Heads are stock and the whole thing was rebuilt just over a year ago. How much boost could a motor like this handle without running the risk of blowing it up.

 

3-4 psi assuming everything is stock and CR is not over 9:1;

 

The compression ratio and piston material (forged, hypereutectic, or cast) will greatly effect the answer to that question.

 

Depends on how hard you "beat on it".

 

I'll see if I can find that info. When the truck was rebuilt I had to do it on a budget so its pretty close to what it had been stock with some minor upgrades. I'll see what I can find out tho
