Thinking about saving money and doing a cam only package from AI instead of the whole h/c package. I want to do the one that is similar to the 847. Would a stock clutch be able to handle the hp from it with 4.10's in the rear? How about stock injectors?

I have a 58mm TB that i purchased thinking I was doing h/c. If I ported my intake, would it make a difference with the 58mm TB on unported heads with that cam?

 

Anyone? Maybe a better question for AI?
