Injector upgrade???

[Maj]

I think there closer to 310 and 380, but like you M i'm trying to remember old info
Depends which cams and pistons, etc, i know of all motor NA bikes making close to 300hp but its a pretty special combo and not realy streetable
at a guess i would say ~200hp if its setup properly std bore hi comp mid size cams , ported etc
no prob with std injectors,
