402 Stroker Is it necessary to do any cooling system modifications when switching from an ls1 to ls2 402? Also wondering if its essential to upgrade the fuel system such as a boost a pump or a whole new fuel pump... what injector size do most people run with 402s? I assume 42# SVO's won't be enough?

for the average street 402 you dont need any cooling system mods.You will need a bigger fuel pump as well as better wiring-such as the racetronix hotwire kit.The 42lb injectors work on most unless it is a real serious piece
