Help me understand rebuild vs crate?

You haven't picked compression or valve sizes and you are picking a cam?
There are several from Howard, Lunati, Hughes and a coujple of others (not comp) that have a 256 with moe lift and more duration at 200 than the generic 262 0r 268
did you say what converter target (will also depend on cam unless you have one you area going to use to get started (highly recommended)

It is a 4sp.

The 390 Scat Kit comes with ICON +4.7CC or +23CC Pistons. So I am on the fence on what I realistically could do for compression. My 7000ft above sea level makes me want to go to a 11.5:1 set up with a +4.7CC piston and 62 CC Indy LAX heads. Just square the block not worry about Zeroing it. Then use a Felpro 1008. But worried that is too much trouble to get right. The +23CC would put it around 9.6. Probably an easier to run set up. But am I undershooting what really I could do for the same money?
