As this is the first version naturally little tweaks can be made and atm Im looking at using the smaller pulley narrower Z head which means I will have to adopt a mounting method on the opposite side like the BMW headed Mini engines do tensioning the longer belt side opposite the oil pump. The water outlet will no longer be on the block above the crank pulley but from the side as previously posted using a small hole within water pump cavity to the block like on second pic.
