Great info! When I took this engine apart it already had the newer style pump. The man I'm building this for had it "rebuilt", but it developed a rod knock 2500 after. Turns out he didn't touch the heads, used the factory pistons and UN-machined crank and cam bearings!! He did put new rings in the highly tapered, and scored cylinders. It also had new rod and main bearings. It had an el cheapo cam, and a lobe was on its way out. He also had the nerve to say that the car must've been hot rodded!!
