The question I would ask is do you want it to be 302ci or do you want a dimensionally the same size as a sbf....(8.2 deck/ 9.5 deck)?
I went with Brent Lykins and got a 8.2 deck block but its an aftermarket block (4.125 bore)....363 final cubic inch. Can spin to 8k.
Rpms is mostly about valvetrain stability.....needs to be light....will cost money, a good bit.
