Can someone hook me up with a direct link to a casting number decoder or break this one down for me? I tried to search for one but couldn't figure out how to find it. Anywho, here's what we found under the grease and grime:
D7TE A3
BM3
I believe the engine is a 1977 351M. We are taking it in to a rebuilder this morning and hope to be back on the road with it next week!
Thanks,
What part did you get this off of ?
All that says is the part was designed for a 77 truck engine had a few changes made to it and was cast on December 3, 1978.
Gorilla, The engine could also be a 400 cid, 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. Will need to pull a spark plug out and check the stroke.
