Get ported heads from Keith Craft Brent. If your lookin for someone to talk you out of going with 12.5 compression in a big block with a big cam.... im not your guy. Take it out to the 428 bore, then get a stroker kit to take you up to 452 CI or so. Oh, and your gonna want Forged pistons, H beam connecting rods, a billet crank, at LEAST a .550 (I would suggest .600) lift cam, oversized valves, Shelby rockers and Tunnel port heads topped off with webers.
Hey, you said "What Budget" and you want bragging rights... so thats my 2 Cents.
