Hey Pontiac Guru's, I have another question for you. I am in the process of rebuilding my engine and would like to replace my cam. According to my books the original part # is 9779067 and the specs are 273/289 advertised dur. and 200/213 at .050 lift. Now i am not sure of these specs, .408/.407 with 1.5 rockers and .449/.448 with 1.65 rockers. How can i tell what rockers i have(they are stock 094 heads). Also if you have any experience with Comp Cams or Edelbrock, which would be a good replacement to give me a little bit hotter cam without having to modify any other parts of the motor(heads and pushrods)? I was looking at the Edelbrock 2157 cam or the 51-221-4 Comp cam, both were recommended by Summit but i just dont know anything about cams to make an educated decision. Help me Poncho!! Thanks All, I cant wait to get the car on the road

1) are you working on a 326 or a 455?

2) what year?

3) what actual measured static compression?

4) What car, how heavy?

5) what transmission?

6) for what purpose, racing or grocery getter?

A radical cam in a 301 or 326 is a pretty mild smooth idler driver in a 455+.

A big cam in a low compression engine is SAD news when you drive it.
