Thread: 350 rebuild

Tweet

I have a 350 chevy engine. block number is 3970014, engine number is CMJ, head casting number is 333882 76cc.
Im wanting to rebuild to get a bit more BHP. I have a pair 64cc camel hump heads will these work on this with plus 30 pistons?

I'm running a tunnel ram with 2 edlerbrock 500cfm, edlerbrock performer plus cam kit and a electronic mallory dizzy.

Any advice would be very greatfull.

The engine number suggests that it only 145bhp.
Thanks Darren

The 64cc heads will raise the compression ratio about a point or a point and a half. It depends on the piston you will be using. Flat top with valve eyebrows(small cuts for valve clearance) will probably work. Most piston manufacturers have information in their piston descriptions as to what you need. Make sure you check for valve head clearance once you have the valve train installed. Good luck.

With a tunnel ram, I would have bet money on it.

If i use the 64cc camel hump heads with +030 flat top pistons does anyone what horsepower it would have?
