HPFP bore and stroke?
Does anyone know the bore and stroke of the LT1 HPFP? I'm doing some calculations for installing an aftermarket cam and that info would be a big help.
I modeled up both fuel lobes and measured the difference in stroke at each angle from the 300 column in the leading edge chart, then adjusted the cm3 per that ratio for each row. (vs multiplying the cm3 column by a straight 138%)
