Made a prototype alternator mount today using the only space we had. Mini Denso version. Plan to build a mount for a different engine inline with the crank. Too many belt driven devices on this engine to do that. It will get a little longer belt, powdercoat and stainless bolts. Water is plumbed in the side of the blocks. Can see the water temp sensor in the down view. The water system is reversed and this is the water exit for the engine. It's very sturdy and lines up perfectly. Can be made for most engine alternator combos.
