Excellent engine you've got there. You're gonna have a blast building and driving that "cool guy" truck. I'm glad to meet you and glad you're here with us!

351M production began for the 1975 model year and blocks were cast in the Michigan Casting Center or the Cleveland Foundry[size=13px]. The 351M was the last pushrod V8 block designed by Ford until the introduction of the 7.3-liter "Godzilla" engine for the Super Duty trucks in model year 2020.[/size]

351M/400 identification confusionThere exists debate as to what Ford meant by the "M" designation of the 351M. Some claim the "M" stands for “Modified” - being modified from a 400-V8 with a shortened stroke - though others claim that the "M" refers to the Michigan Casting Center, where the 351M began production. Some say that the "M" designation has no official meaning, and that it was just Ford's way of distinguishing the 351M from the 351C and 351W.

"it was just Ford's way of distinguishing the 351M from the 351C and 351W". While I think this is probably the truth, I remember reading somewhere about certain blocks from the "Midland Foundry" having a problem with cracks, and the Michigan foundry blocks were ok. Maybe it was "Just My Imagination"
