1977 Engine ID

Excuse me for my ignorance but I have very little experience with these vintage Fords. I own a 96 and 89. My uncle just called me and gave me his 1977 F150. The body is in good shape and the engine and auto trans were replaced 20,000 miles ago. He doesn't drive much. My question, What size V8's were in these trucks. He told me it was a 360. I didn't think the 360 was used in 1977. I will take a quick look at it tomorrow evening. I know my question is vague but hopefully I can learn more tomorrow. Thanks Matt

It most likely has a 351M. Could also be 302, 400, or 460. Look on the valve cover & it should say what you've got. The VIN will also tell you unless your uncle swapped in a 360 he happened to have laying around when the old engine went.

351M/400 335 series: intake is 12.7" wide the 351C is narrow.
351W/302/5.0L 6 bolts on trapezoidal valve covers. Thermostat housing on intake. Exhaust bolt holes horizontal.
429/460 385 series: 7 bolts in rectangular valve cover

-There are other indicators but these are enough to distinguish engine families.
