I'd say go stick, but it does take some practice getting shifts as quick as possible. Now If I was going to do this! heheeh! definatly a aluminum 427 twin turbo around 1000hp, backed by a lenco 5 spd planetary tranny (shifts faster than an auto! ) move the motor back 6" or so from the l6 position for better weight dist, this could be done with a glass' firewall, definatly switch susp over to tubular components, a-arms 4 link rear, box frame where it needs it and replace standard x-members with large diameter tubular ones, much stronger! move all stuff possible to rear of truck, gas tank, battery etc. and heres the killer, instead of running 2 rear slicks run one giant super wide tire driven from the outside ends steamroller style! that should give you all the traction you need!
on second thought, tubs will do!
Have fun!
