I did the impossible and solderd a copper fitting to my Al top forthe center inlet. Going to hook it up tomorrow right after I ship Fixittt the Z4. The Z4 is actually doing pretty good after I milled the channels out. Anyway I will have a pic of this disaster looking top tomorrow.
This is just going to be for testing. If the block cools to my satidfaction I will make a manifold for the top somehow to route to the outlest into one. Not sure where to place the outlet though as there isn't much room with the center inlet.
