Thanks again Chevy 37 for all your help! I really appreciate it!

I called GM and they told me that they do have them in stock, for 546$ Can (exchange fee...ugh!)

So that would give me what's needed?

Do you have any advice as for what kind of crank i should put in? What duration?, What kind of carb? (Someone told me only Ed makes them now???)

From what i read this week-end, i need the right heads, with the right cam, with the right exhaust sys, and with the right intake...

Is that all?

Thanks again!
