Original engine
#1
I just purchased a 72 Mach 1 351c, how do find out if my engine is original? Thanks for accepting into the club.

If it's original it will have a partial VIN stamped on the rear of the block, on the driver's side, just below the head gasket. It'll take a mirror, cell phone camera, or inspection camera to see it. The casting number and date code are on the other side of the block above the starter.

Thanks I will look for the number. This is the picture I know it’s been wrenched on. But would be cool if that is the original block.

Hello, welcome from France.
You can check as well a small number on each corner of the heads. If you find 4 then they are 4V heads.
