Ok don't beat me up to much on this lol but I was curious I have a 96 5.2 that I wanna build curious if yall might have a rough estimate about what the HP might be? Stock rotating assembly, turned and polished crank, journals aligned honed, 0 decked, CR will be around 10:1 with flat tops, would like to get away with a 509 purple cam with springs, iron heads that I'll mildly port match, stock 1.6 rockers, and a 700cfm carb and full tube headers

Keep an eye out for core shift on that one
But since you mentioned port matching I am assuming you plan on addressing that,should the need arise
