Can't find s/n on engine
I have a similar problem to the post by merc390. I recently junked out a 1973 F600 with a good running 390 (I think). I have checked the engine all over and can't sem to locate a stamped number on it anywhere. I did manage to get the following casting numbers and according to the info provided in merc390's post, it would be from a 1967 vintage car/truck. I'm quite sure the engine was replaced because the left exhaust was interfering with the clutch linkage and the rear motor mounts had been modified. Anyway here is what I found.
Casting Numbers
1. Intake manifold - C7TE9425G (also 7M15)
2. Left Exhaust manifold - C8AE9431B
3. Right Exhaust manifold - C5TE9430C
4. Right Front side of block just below head - C7ME
5. Left Front of block beside waterpump - 47 & 352
6. No numbers on Vibration Dampner just the word FoMoCo
I want to sell this engine but it would be kind of nice to be sure what it is.

Well.. The C7ME block was used for 428 passenger cars, as well as the larger truck line. Here in lies the problems with trying to identify a motor by it's cover. Take a look at the size of the crankshaft snoot, the big trucks used a crank with a 1 3/4 inch snoot. The best thing to do is pull the pan and get the stamp numbers off the crank, that will get you closer to a good guess.... Of course I would tell you to pull a head too to see what the bore is also, but that might be pushing my luck

Casting Numbers
1. Intake manifold - C7TE9425G (also 7M15) Cannot find a cross reference #.
2. Left Exhaust manifold - C8AE9431B = C8AZ-9431-B Fits: 1968/71 390 LTD & 1968 T/B; 1968 LTD 428; 1969/70 428 P/C
3. Right Exhaust manifold - C5TE9430C = C5TZ-9430-A Fits 1965/67 F100/350 = 352
4. Right Front side of block just below head - C7ME
5. Left Front of block beside waterpump - 47 & 352
6. No numbers on Vibration Dampner just the word FoMoCo

An FT intake manifold will not fit an FE engine
352 vibration dampers have ID numbers, 360/390's do not.
Is there any ID number on the flywheel like (FE) C5AE-6380-J or C5AE-6380-K? / FT: C4TE-6380-K or C4TE-6380-J or C5TE-6380-D
Measure the bolt circle on the flywheel, count the teeth.

Thanks guys for all the input. it has been very helpful and good info for future ref. The situation is this, I checked the stroke and it is 3.75" (roughly) and that tells me that iit is at least a 390. I can easily check the crank snoot to see if it is a FT or FE series but despite my personal curiosity I don't really want to open it up to check further. Since I have it listed in ebay as a 390, I guess if it is bigger someone will be getting a bonus. If it doesn't sell right off then I might try to satisfy my curiosity. Thanks again guys.

Just take a plug out, rotate the cylinder to TDC, insert a piece of stiff wire and mark it, rotate that cylinder to BDC and again mark your wire. Remove the wire and measure the stroke. Knowing the stroke on the crank will narrow down the possiblities of what the engine could be....

Intake sounds like the old "T" intakes comparable and more or less the same to the "S" intake. Both 2v and 4v were made. 7M15 is the date code of 67/Dec/15th. Do you see a "T" cast into it by the casting number? What casting number is on the heads? Also some balancers/dampners have the number on the inside. You'll need to scrape off the paint and grime to see it. Some are stamped on the outer ring too. Once you post the head numbers that will help tell FT from FE. And if your selling buyers would want to know. Check the stroke like Dave said. Easy nuff to do.

I don't see a "T" on the intake but there is one on the RH Esh Manifold. I had already checked the stroke and it is 3.75". I still can't find any casting numbers on the heads. All I can find is a DIF next to thefar right plug hole. Here is a link to my photo site on Flickr http://www.flickr.com/photos/pitlockboy/ once on the site click on the (390 or Not) set to view. I had a brain storm and hunted up my old Motors manual 1966-1970 and find that the F600 never had a V-8 and since the engine apparently is a 1967 it obviously was a transplant. According to the Motors manual I thought that getting the Dist. number would narrow it down but , the number on the dist. doesn't even come up in the listing. Not sure why but phto of it is in my photo set. I will post all of the numbers that I have so far in just a bit once I get it reoganized. This might help all of you who are trying to help me out.

Head casting numbers are between the center 2 sparkplugs. Sorry I forgot to mention that. Like C7AE-6090-A or C8AE-6090-H would be common to find. Looking at the pics you have it looks like a FE.

I was just down getting ready to move the engine back in the shop (it's a lot warmer there 28 deg outside right now) and I don't know how I missed the great big T on the intake manifold but it is there. I have a buyer if it is 390 and he wants me to confirm by measuring the bore. I'm going to drop the pan and see if I can get a measurment with inside calipers. Thanks again

LOL well at least you saw it. That was the std FE intake used. You can look at the edge of the crank counterweights for a "2U". That was the std issue 390 crank used from late 66 to 73. There is also 3U and 2UA and about 13 other casting numbers all from early and later cranks. But if it's stock my bet would be the 2U. If you find something different post what it is. We'll figure it out. But with your measurements it sure sounds like a 390. Good luck.
