540 build

I used the 440 source 4.5 stroke kit. The only block mods I had to do was some clearance grinding around where the sump pipe threads on. I used the stock type oil pump with the milodon single line spacer between it and the block, longer driveshaft deal.
I didn’t do any oiling mods to the block besides changing the pump suction, but mine was never intended to be a high rpm super high horsepower build.
