C3M?? block casting ID help
Just picked up a engine and am wondering what exactly it is?
Block cast is c 3 or 8 m and the rest I cant tell. the date code is 5d18
crank is c4ae-b also has a 1 and a Z
rods are c3ae-c
pistons c3me6110a
heads c4ae 6090-g with matching date codes 5D15
any help would be appreciated
Thanks

Ford pistons sometimes had the displacement cast into them near the pin holes. A quick check with a dial caliper will tell you the diameter. You already know the stroke with a C4AE crank. A C3 block I would think would have two mount holes per side. But I could be wrong on that.

The motor mounts have 3 bolts. The block casting
Is poor and hard to read. The first letter is C 2nd could be a 3 but it's messed up
3rd is clearly an M the rest is a mess. It's not important though
It's a nice 390 that's all that matters. I was just
Wondering about pistons and CR of them.
Thanks for all your help
here is the piston.....
Anyone in New Jersey of New York that can recommend a real deal FE builder?

More'n likely that's a C6ME-A block. Never seen one that bad on the outside though. As such, I doubt it's an untouched assembly with those heads, crank, rods and a C6ME-A block. But you never know with Ford. Clean the piston top off and see if there's an overbore stamped into it. Looks like a std 9 to 1 piston though. The early 10.5 to 1's had a shallower dish and no valve reliefs.
