Hello everybody! Sorry for the long post. I recently purchased an FE engine for a great price.... if I could figure out what it is! So about a couple weeks ago I found an FE engine for sale, the owner had recently started living on the property of a friend that had passed and this is one thing the person left behind. The seller claimed that the engine was fully rebuilt by their friend that had passed so I decided to go look at it. When I got there it was alllllll the way in the back of a dirt floor shed (ugh), so I lifted it up and pulled the oil pan and the crank read 2u. Perfect, a 390 and it had the 390gt 14 bolt heads. The cylinders looked like they had been bored and that was all the confirmation I needed to buy it. I have now since drug it out of that hellhole of a shed with my cherry picker. (It did not come willingly)
Yesterday I decided to pull it apart and figure out what it had been bored out to. Once I got the a head off I measured the bore with a caliper and it read 4.0800 was the widest I could get, the pistons read 30 over so it had been rebored. Now I decided to measure the stroke with the caliper and got something like 3.9100-3.9200. This is where my confusion lies. It has a 2u crank which is a 390 crank so it should have a stroke of 3.78, I thought. I then decided to try and determine what the block might have been, I know it’s almost impossible to really know what it originally was but it had C7ME-A on the block which according to ford was a 330 or a 428 but who knows. I then looked at the date code below the oil filter adapter and was confused even more, one plate read “E” and the other read “7H” and I thought the date code was 3-4 characters. So if anybody had any idea what I’ve got I would greatly appreciate your input! Thanks
When you measured he stroke, did you measure from the deck to the piston at BDC? It looks that way in your picture.
If so, you are adding the piston to deck clearance. It appears it could be .130 in your case. That would make it a pickup 390 with pistons having a 1.66" compression height.
It's not clear from the pictures if your piston is really that far down the hole, but make sure you are measuring piston travel, and measure the distance from the top of the piston to the deck at TDC as well.
85' is right - looks like that one picture you took shows how far down the piston is in the hole. Now, bring it to TDC, and measure again, and subtract the two numbers.
Looks like you got a good 390 pickup truck engine. Low compression, though. Those pistons look to be Badget pistons according to the P711 on them, and a quick look around the 'net seems to indicate 8.6:1 compression.
Ahhh yes that makes more sense. I was having my friend measure and when it didn’t add up I didn’t question what he was going haha. Thanks for the help! I looked at the cam and all I could see was what I believe to be SF (F might be an R) 63 with 28 directly below it and on the other side it read CWC with an E directly below it.
So I found thoes last characters on the end of the cam transmission side, I went back and looked more and between lobe 2-3 what looks like I-6 or maybe 9-I and between 8-9 I found D2 and 180 of that I found 02 or C2
C7ME is an FE engine block cast in 1967. Date 7H = August (H) 1967 (7). If it's 7HE, it was cast during the 5th week (E) of August 1967.
A = January, M -= December, the letter I is skipped.
The "E" in OP's pic is the shift identifier it has nothing to do with the casting date. Other common shift identifiers at the Dearborn Iron Foundry (DIF) during that period are E1, W and W1. Strangely the casting day of the month spot is blank on the OPs block.
