It was originally cast as a Mercury block, but it could have been sold in either a Ford or a Mercury. As was said, my book shows it as being either a 67-70 428, or a 330MD FT block. I'd say it's probably the 428, but check the bore to make sure. Books aren't ALWAYS right.

My C7ME-A is a 410. Like Sean said, you can't tell what it is without popping the pan to see if it has a 3.98" stroke crank (1U, etc.) or measuring the stroke with a dowel, and then you still have to measure the bore. Ford used that casting for just about everything in that vintage. But good luck, you might have a goodie! Steve

where are you guys getting its either a 410 or 428, like a previously posted, i found the same block in someones grove all original and it was a 390, yes it could be a 410/428 but it could also be a 390.
