Hey all, just hoping you guys can help me out with what I have here...

I just bought an engine that's suppoosed to be a 390, although I haven't checked the stroke. I can see through the spark plug hole that it has .040 pistons in it.

The engine has an odd looking flat oil pan and front mounting bracket on it.

Here are some of the numbers I found on the block and heads...

C7ME-A
E
7M19
?4 DIF
39
352
8J30
C9AE 9425-B
D2TEAA


Here are some pics of the numbers, I may have misread some of them them...

And here is the oil pan and front mount bracket. What's the deal with these?

It's either a 360 or 390. There's a remote possibility it's a 410 (390 block w/ 428 crankshaft) 7M19-- block cast on Dec. 19, 1967. Heads are D2TE's which tells me your engine has either had the heads replaced and/or the engine's been rebuilt. Those are 72-76 heads on a 68 model year block. As for the oilpan and bracket, those are FT truck items and tells me someone had this engine in a medium duty truck (F500-800) The bracket was the front engine mount. The oilpan is an 11 qt capacity pan, it also fits on FE's in the smaller pickups (F100-350) Also looks like it was never run after the rebuild, the piston in the sparkpulg hole is too clean

 

C7ME-A : Mercury 1967 Casting Number

 

But it's not a Mercury specific number. The block was used in more Ford's than Merc's. The "M" only says the engineering costs were assigned to the Merc division. This same number is found on 360. 390, 410 and some 428's.

 

OK...I don't remember ever reading that. It'll be interesting tho to see what it turns out to be.

I'm not arguing...but I've never seen a Merc casting number on a 352 or 390.

 

Yikes! The cost of my oil changes just doubled!

Would .040 over pistons in a 390 make it a 398?

I kind of like the thought of having more oil since this is going in my '79 Bronco that may see quite a bit of off-road abuse. And yep, it's a fresh rebuild and hasn't been fired yet. There is surface rust on parts of the engine, so I don't know how long ago it was rebuilt. I think I remember the guy saying something about it was built for a 25 foot box truck.

I paid $300 for this engine, a 10.25 Sterling rear axle, and a receiver hitch for my '79 F150... so I guess that ain't too bad?

 

I know there were special oil pans on the NASCAR stuff...and there was the FE finned aluminum oil pan you could buy over the counter that had that rectangular addition to a stock pan...but steering components might interfere on some of the F100's...with an 11 quart pan.

Don't the Bronco's have a reverse sump?

 

Ya, the Broncos use a rear sump pan. Mine is going to have about 8 to 9 inches of lift, so hopefully the pan will clear the axle. If not, I can swap the pan off the 360 that's in it onto the new 390.

 

The mid 70's 4x4 360/390 had a rear sump pan, not much different in size or shape than the 11 qt pan. I have one in my shop. $300 is a steal for all that stuff. Be sure and prime the engine before firing it. Might be a good ideatoo, to pull the intake and smear fresh cam lube on the lifter bottoms (none on the sides) Flood the lifter valley with oil before replacing the intake.
