1978 440 parts needed (budget build)

I know alot of Mopar guys like the Keith Black pistons, I opted for the Speed Pro set that I got with a Summit rebuild kit, it was less expensive than what I thought it would be, I ended up spending about $900 shipped. Full rebuild kit, forged pistons (they don't sit deep in the hole like the original ones) w/ moly top ring. That was including the MP cam kit, Comp Cams double roller timing set, and high volume oil pump. If it was an RV engine your original pulleys may not line up if you swap the water pump housing, but I think at that point you won't have a problem finding stock pulleys / accessory brackets from another vehicle that will work.
