small block build ?

Use the smaller cc'd head for max quench effort and a 750 cfm carb. Choice is often by personal like of the carb. Be it a Holley or Edelbrock, what ever you like to work with is it!

The cam is small enuff to work very well with either carb. If your open to any carb or no exper. with carbs, a basic Holley 750 vacuum secondary carb will be just fine.

This combo if well tuned should be good for 400 HP.

Oh, on the rockers, I have a set of Comp Cams basic roller rockers in use. Inexpensive.
