Is this LA360 XE268 cam kit deal good for my combo?

Hey Rusty - I'm curious why you think he's got low cylinder pressure. It's a stock '78 360 bottom end with a mild cam and he's got 150psi cranking pressure. That's seems like more than I would expect from a stock low compression 360, even with the milled heads.

What would you expect from his engine in terms of cranking pressure?

I'd like to see 170-175 and he can get it there.
