The engine features my 700 lightweight pistons, stage 1 porting, 153x1 cams, Uni pods, and a "hybrid" jet kit consisting on Dynojet needles (hack, spit... but that's what it had when it arrived) and bits of brass that I had laying around. Jetting for the under-engine exhaust is way... WAY different than normal. Good luck to you if you go this route yourself.
