MaSnaka, I’m generally conservative by nature and my 428's build reflects that. I took the bore out to 4.155 and chose the “medium” SCAT stroker of 4.125. That works out to 447 cubes, and on this board that’s a reasonably mild build for a 428, but it would tax most 390s. If given the choice, go with the 428. It will open up more build options for you and the increase in price is not very much; certainly not sideoiler type money.
