Build an 800hp big block with a fogger and EFI. I'd spring for steel, paired shaft rockers and G Force GF5R or something similar. If that guy in the GTO can make it all of the way from Canada....
Another option would be a couple of turbos on a 650-700hp long block and stay under 15psi.
From a maintenance perspective I could see where a person would be time/money ahead using a wedge platform instead of the more complicated hemi valvetrain/intake manifold designs.
If I were going this direction I'd do a 540 Cube Indy 573-13 deal with steel rockers, Ti valves and a Holley Dominator EFI with CnP.
