The centerpiece of the engine is the A&A reproduction Max Wedge crossram intake manifold. Copying the look of a vintage Mopar super-stock piece, it’s cast with smaller 440-size port openings, so it fits commonly available production wedge heads. With dual Edelbrock 500s and A&A fuel line, gaskets, throttle cable, and linkage kits in place, you’ll pay just under $2,500 for this stuff. Or you can go with a swap-meet Torker and rebuilt double pumper for one-tenth the coin. Either way, your 512 is going to fly.
