I put a zz 350 in a dirt track modified a few years ago, only thing I did to it was a cam change and a alky carb and it ran like a banshee, around here most of the hotdogs run 430's with brodix heads and I could run with any of em on the 1/8,1/4 & 3/8 bullrings. Took it to a couple of mile shows " Duqoin & Springfield Illinois" and got my butt waxed,
I would say it would be a killer street motor.
