Mystery 440 block

Mystery 440 block - 11/24/14 01:52 AM

I have a 440 block with a casting number of 2536430, which, by several sources, makes it a 67-72 block.

The pad on the passenger side at the bottom is blank.

The top pad has markings in font much larger than I have seen on passenger cars - photo attached. There are coarse machining marks; don't know if that's factory, or not.
Marine block, perhaps?

Anyone know?

That means is was cast after the 1969 car where being built and sold

as far as the meaning of the marks on the pad

Good luck, hopefully someone more in the know on pad markings will chime in

I've never seen a factory block stamped in that direction. All the ones I've seen are stamped to read correctly as if the were installed in a car and you could read them from the radiator side. Also the font does not look like anything I've seen from the factory. I think someone just stamped the motor for their own purposes.

Nope. Nothing stamped on the bottom.
