Might not be cheap, but here is how I would go about it.
Shortblock.
=New iron World block.
-Callies/Crower crank
-Oliver rods.
-Pistons- several mfgs with excellent Hemi inventory.
Heads;
-Give a call to Jeff at Modern and have him set you up with a set of CNC'ed heads.
- Barton/T&D rocker setup.
Intake
Ported Barton crossram with a set of Dale Cubic prepped SS carbs. There are better induction setups out there, I just like crossrams, especially on a Hemi.
These are some of the items I would choose. Not a budget build, by any means, but not bank breaking either.
