With a T-56 and the intent to slaughter ricers...I wouldn't run anything taller than a 4.11 rear end, but that's just me. 6th is still roughly a 2.06 gear then. Gonna need a nice new clutch to go with it...replace most of the body panels with fiberglass...run aluminum components whenever you can...definitely start with a coilspring truck...try and cut weight however you can. If you've really got money/time to burn, box the frame...it'll add some weight back but it's worth it.

If money really was no issue, I'd put a 427-cube sleeveless-block LS6-based engine under the hood...the stock 348-cube LS6 is good for 405hp right there! Yet it'd be smaller and lighter than a regular smallblock...

You'd be looking at 450-500hp, with a lot less weight than stock, and a lot better handling.
