printable v8 engine (probably working)

all the engines i have seen have been basic block, crank, and pistons except that one inline 4 that is up and that one is wonderfully and very nicely done but it is not a v8. so i build a v8 now i do not have a 3d printer so i was saddle unable to test print this but something i do know about the model is that i would use steel/brass rod for some of the parts i have in the files. the rod's to hold the rocker arms in place straight parts of the crank shaft the push rods really should be steel or brass. now this is not a print and put together and you are set to go thing all models will need some work when i modeled all the parts i did so with very tight tolerances the pistons are going to need to be sanded and likely most of the other parts are to so don't think of that as a print and get going think of it as a plastic modeling kit like you buy at the hobby store. the reason for the model is that i wanted a model of a engine with all the parts that work that is not a inline 4 meanin
