Motor makes a little heat but I haven't let it run long enough to move to temperature gauge..the block is filled to the bottom of the water pump holes..I called rons and that's what I'm going by great guys there but as was said earlier I think each is going to be different but he did give me a baseline to work off of..my buddies car is blown with injection he helps me as much as he can but his is alot different being blown and other stuff ..I just don't wanna mess this thing up again last year cost me having the crank fixed from cylinder full of alky.
