No problem on the question you asked, here is fine.....I re-used the case and the heads....everything else is new.....I sent the heads off to get them ported and polished with new valve springs and valves, new rods because the old crank was VW journals now this one is Chevy journals, different new cam, new lifters because the lifters stays with the cam, new rockers, new jugs and pistons. You can pretty much re-use everything except the crank and rods, you just have to get the block cut and clearanced for the 90mm crank and open your heads up a little bit, as far as the cam goes, it depends on what its got to start with, if it is a W-110, FK-43, or somewhat close to it, you can re-use it, it is all up to the owner on what he wants, there is plenty of info out there on choosing the cams you like on that particular engine, you can re-use the jugs and pistons, just re-ring the pistons and make sure they are in good shape and the jugs, you will have to space the hell out of them to make up for the longer stroke, I'd preferred to use Jaycee long barrels for the 94mm bore because it is extra long on the case end to where you can have it cut to fit your longer stroke and eliminate the use of spacers. Let me know if you need anything else and thanks for the comment on the truck
