I was given a couple of what appear to be FE engines from behind a friends house. The only numbers I can come up with are on the rear of the block. They are 26 352, 58 352 can anybody help in id'ing these blocks?

The Guru's will correct me if im wrong!! On the back of the crank!
If it has a square on it? it supossed to be a 360!
And if it has a Half moon shape on it..Its a 390!
If not as mentioned above you have to check the stroke!!!
3.500 for 360 and 3.780 for the 390??
I think thats right!! Good luck!!! Russ!!

Rapid, you got it backwards.
A half moon shape was machined into the end of the 352 and 360 cranks in order to perform machine work on the crank. The 390 and up didn't need this because the rod journals were further away from the crank centerline which allowed adequate clearance for the machine work.

I'll let them go cheap, I have no need for them as I have perfectly good 300/6's in my trucks. Can deliver if distance not too great.

BB, how often have you seen this? It must be extremely rare.
Still, anyone can be confident in their search for a 390 - 428 in knowing that any FE lacking this half moon is definately not a 352 or a 360. That is as solid of an indicator as anything if someone is looking for at least a 390. Search and purchase with confidence!

PF, every '65 and earlier 390 crank I've seen had the half moon. I'm guessing that in '66 when the 428 crank came out they stopped with the half moon since the throw was so big the flange didn't get in the way of hollowing it out and realized they really didn't need it on the 390 either so that's when it changed. Just a guess.

That is good to know BB. I am always learning something new about these old FEs.
What you said seems logical in why the 390 cranks started out being machined and then stopped on later 390s.
