im currently finishing up my 416 build, im trying to figure out what jets i should run for break in, because in a week i got to the dyno for fine tuning. i have a wiseco 11.1 piston, full exhaust, k&n without airbox lid, port and polished head, stage 1 cam, and removed choke from carb, what jets should be safe for break in, i just dont want to hurt it, oh and i live in michigan if it helps at all, thanks

ok, one more question, i have a 42 keihin pilot, and then i have a dynojet kit, when you say start with a 165 or 170 are you refering to dyno jets? and with the choke removed from my stock carb, are they refering to a 42 keihin jet, thanks for the help

I'm currently running with a dynojet main and stock everything else. Dynojet has a different numbering system than keihin, the numbers I gave you refer to the keihin main jets. The choke only adds throttle response I don't think you need to up the main cus of that but if so do it.
Use a 42 keihin jet with the jets your gonna put in.
