Will the stock vortec injection work with the engine in my sig. Im putting it together tomorrow and want to know if i need to find another way to fuel it. And will i be able to break it in without a tune?
your biggest problem will be getting it tuned for that cam,hopefully you did some head work and valve springs for that cam and the 1.6rrs your looking at around .600 valve lift.never seen anyone run that big of a cam in a l31.with a stock intake.
