351M indentification
I'm new to all this and I am looking to buy a '77 F-150 4x4. The guy claims it has a 352ci but that would mean it was a transplant. I suspect it to be a 351M because the heads look similar to the 400. Can someone tell me an quick, easy, foolproof way to indentify the diff. between the 351/352?
Thanks in advance...

351C/M/400 335 series: 8 bolts in rectangular valve covers. Timing chain housing is part of block. Thermostat housing on block. Exhaust bolt holes diagonal.
351M/400 335 series: intake is 10.7" wide the 351C is narrow.
351W/302/5.0L 6 bolts on trapezoidal valve covers. Thermostat housing on intake. Exhaust bolt holes horizontal.

There are other indicators but these may help.
