Thread: FE Engine Identification

Tweet

After digging a little deeper the C4AE-A could also be a 330HD,391FT or a 361FT also besides the 352. The 6015 is correct and just the internal Ford number for a engine block. Now the 330HD has a 3.875 bore and the 361 and 391 a 4.05. Both 330HD and 361 share the 352's 3.50 stroke. The 391 a 3.79 stroke. Also the 361 and 391 used a forged steel crank and some 330HD used iron cranks and some forged steel. Also the 391FT crank had a larger diameter snout than the std FE crank and used a iron timing cover vs the aluminum FE cover Whatever it is it's not a 390 PI as your being told but sounds like it might have 390 internals. The 330HD,391 and 361 for 64 would have reinforced crank webbing and the crossbolt nubs but no crossbolts. The 352 block would have the std crank webbing and maybe crossbolt nubs. There is really no other way to check the bore without taking a head off. I'd also take the oilpan off and get the casting numbers off the crank and rods. Ford is famous for using the same casting number on a varity of blocks as you can clearly see. As you stated the engine is 40 years old and a lot can happen between then and now. I'd have to say should you want to venture forward on this you should really look inside to see what's what. It can all be ID'd by the part numbers easily. If the seller does not agree to this he obviously has something to hide but most guys should be fine with it. He might even be interested in finding out what it really is himself. Confusing????? you bet but it can all be sorted easily. G.
