Right now it has a chevy 383 with a weiand 177 supercharger on pump gas. No nitrous plans in the future, id like to switch from a roots blower to a centifugal one though. I've been running a my stock light duty turbo 350 trans with all new tci parts, and a 3500 stall. I tubbed it last year and put on some et street mickey thomson 15x18.5x31's and a dana 60 rear end with 4.30 gears. I wanted to run a 29 inch tire so it wouldnt suck up all my gear but nobody makes a wide 29 or even 30 inch tire. You cant tell i tubbed it unless you notice the giant tires, everything looks stock and i kept the back seat.
I shoulda built a bigger stroker, or maybe a big block. but the 383 will haul arse. It ran in the 11.6 nat aspirated
