Your goals are limited budget, and stroker is out, smoke the 275's, low rpm, moderate fuel use, other real race toys in waiting, 2200 904 converter, e body, currently good running "crate"? 360 motor, 3.23 RA, if I read it right, you are already there?

One thing stands out to me, ditch the choice of OEM exhaust manifolds for real headers, weight, efficiency, etc are worth it. I also don't think the cam choice in this application is that critical, more ball park choice, as I bet the goals will upgrade in the future, quickly obsoleting any critical cam choice. twocents

Reality check, that half the population is smarter then 50% of the people and it's a constantly contested fact.
