1979 350 (4 bolt main): $100.00 400 crank with rods: $100.00 now to adress some issues. i've been told 3 different things. Thing 1: 350 bored over = 383ci Thing 2: 350 with 400 crank = 383 stroker Thing 3: 350 with 400 crank bored .30 over = 383 stroker which is true? next, i've been told that people have had problems with 400 cranks banging on the inside of the 350 block. is this true, common, false? do i need to have any grinding done to clear the crank? next, what about an rv cam? is something like this recommended, possible, stupid? next, how much rebuilding should i do? i'm figuring new rings, gaskets, etc. what about pistons, lifters, headwork? FYI, i'm planning this for my next fj40, big axles, big everything else, 39" boggers.
