Re: Piston coolers

There will be problem. This is because the old block has the piston coolers to transfer oil to the piston. But the new block does not,meaning the new block uses the type of connecting rod which has linkage to transfer oil to the piston from the crankshaft. So its better u dont use that block or you consult where you bought it first.
