Engine is a modular short stroke V8, designed to be machined, so the crank case is separate from the sleeves, there is no oil drain from the head to the crank case, it's easier this way to control vacuum in the crank case... I modeled a dry sump pump as well that should go onto this... some missing parts but overall reasonably complete... The front cover is messed up sorry about that, but simple part to fix.

This would accept 2 Honda B-Series heads or my head that I uploaded with some mild modification to the oil drain back holes(weld some pipe in) to tie them directly to the dry sump pump.
