Ok got another one for ya. I pulled out my cam on the engine iam rebuilding and would like to know what the specs are as to know if i need to change to a better grind. The numbers on the cam are 643.CPC. BC.55 iam not sure if this is a stock cam or not, but i think CPC stands for CHEVROLET, PONTIAC, CANADA. Any help would be appreciated. Thanks Chad :conf:
