It's a 1968 FE or FT block.

The C7ME is common to all FE and FT block castings, whether 330FT, 352, 360, 361FT, 390, 391FT, 410, 427, or 428.

The one you found is from the 1968 model year, so it won't be a 352 or 410, but it could be any of the other displacements.

You'll want to look on the flywheel face of the block for any large "scratched on" text characters which protrude from the block about an eighth of an inch nad are generally 2" tall or more. An "A", "C", or "X", indicates a 428 block.

If the rear face has "66-427" marked on it, it might be a 427, but more likely it will be a regular FE displacement which used the 427 rear panel only,as there are lots of these castings out there. If it is a real 427, it'll also have tall scratch marks such as "I", "II", or "H" on the rear face. Don't get your hopes up, however.

Check the bore diameter. That'll get you close to the intended application. If you have a drill bit, use a 15/64" bit to "feeler gauge" between all the cylinder jackets (gotta remove all six core plugs). If it fits between the cylinder at any single reachable location, it's likely a 360/390 block, if you cannot find even a single location that the drill bit fits, it may be a 361/391/428 block.

This info is just for starters. Further isolation of the block can be done by inspecting the cranksaddle webbing and looking for text on the floor of the water jacket inside the center core plugs or opposite the long coolant slot in the deck.

Good luck.

Shoe.
