Hey guys, I was taking apart this '92 350 I just got for free and wondered about the head chamber cc rating. Here's the casting number: 14102193. I talked to a friend of mine and he said they are a 70 cc casting and make a stock '92 350 have the CR of 9.3:1.

www.Mortec.com doesn't list the cc rating either. Anyone have any idea what they are? I need to order pistons, but wanted to know the cc of the heads before choosing CR.

The 350 is going to be used in my '87 Camaro (305 LG4 Q-jet) to replace the 383 that won't pass SMOG.

Any help is thanked.
