I picked up a 416 stroker kit for a 390 FE last month from a friend of a friend. The guy said he bought it but never installed it. Well im rebuilding my 390 FE so i picked it up. Its got cast pistons and rods and a scat crank. The rods #'s are stock 428 rods. And the pistons i have no idea other than the size are .060 marked on top. Do you guys think those will last me? Its goin in a 75 F100 4x4 prolly take it to the track once or twice a month just to put it in its pace. Rest gonna be city driving mostly. Ive looked hard and the only place i found that had forged pistons for the 390 .060 over was kieth black and they were to tall. So what do you guys think?
