I have just joined the site off of a recomendation from a friend. I have a long history of love for the pantera!!! I purchased a 68 gt Mustang awhile back and hoping to find the original 390 I found something under the hood I am not sure what it is. My friend who knows alittle about Cleveland stuff looked at it but was not sure as well. It looks as if the valve cover is a stud girdle and it has a alum Cleveland head on a Windsor block. I am looking for some input on what I have. I dont have much need for the engine due tot he fact that it was not a S code 390 but it is very neat looking!!!

That's a collection of mid 1980s Ford Racing parts.

Those are Ford/SVO heads, they came in 3 versions with catalog numbers M-6049-A3, M-6049-B351 and M-6049-C302. Can't tell which version from the picture, need to see the casting number below the valve cover, or we might possibly deduce which version by the dimensions of the intake port. The casting number is a little different than the catalog number, it will read something like E3ZM-6049-C3.

Those valve covers are Ford/SVO valve covers, M-6582-A351. They're magnesium, and they sell for big bucks on eBay. They were originally intended to act as a rocker stud stabilizer, similar to the function of a stud girdle. They're valuable today simply because people think they look "cool".

The intake manifold is a Ford/SVO manifold cast by Roush Engineering, either M-9424-A331 (351C only), M-9424-A351 (351W only) or M-9424-B351 (9.2 deck 351C OR 351W).

Does that block have a Motorsport/SVO number cast into it by any chance? M-6010-xxxx?

You won't know what the displacement is until you measure the bore & stroke.

Looks very similar to what I have in my Group 4. Photo, specs and builder are shown in the link below. From what I have been told, those bolts up through the valve covers help keep everything lined up and in place beyond 6,500 RPM (not sure if that is BS or what). Shine that puppy up, it will look like mine when done. Smiler

It is likely given the era these are the last in the series of FMS heads that used standard C valve train and were the later iterations of C302s. There were actually heads that each carried C302, C302B and several iterations that carried the C3 designation in the series of heads that used standard 335 Series (Cleveland) valve train. There was also a more contemporary head that carried this number that was significantly different. All had subtle variations to one another but in general they were the smallest port volume configuration of the high port heads offered at the time. The C series were advertised as having 212cc intake runner volume, 95cc exhaust, and 62cc combustions chambers and were optimized for smaller displacement engines. Most of these heads have been through so many hands by now few bare any resemblance to these specs.

Not sure if you are generalizing, but all the FMS blocks were more Windsor than anything else as far as features excepting main bearing diameter and possibly deck height (9.2 version). Do you know the deck height? Be advised that FMS blocks of the era were not always clearly marked. There should be a part number down by the motor mount. Is there a part number on the intake manifold (maybe M-9424-xxxx)? A picture of the intake manifold flange thickness can sometimes signal deck height; thicker suggests 9.5. If there was a good picture of the front of the engine that could also help. If it is a 9.2 deck engine, odds are very high it is an FMS block.

If you don’t know what you have you'd be better parting that out if you want to maximize your take. Unless you just want to unload it, you're not likely to command premium let alone market for a collection of unknown parts on a used engine.

My 2 Cents.

Best,

If I needed an engine and if it is a build like mine, I would buy that thing. I love the engine in my Group 4, reliable, fast, and thumps like a mad man. As George says, just those valve covers are a fortune now. Last I saw, there was a set on ebay that sold for $1,000 about a couple years ago, although he wanted $1,500.
I did get a # off the intake M-9424-A356. There is no part number by the mount and no screw in freeze plugs. But I did remove the intake just to look did see two things the block has the old FoMoCo(dont know if that dates it any or not) and the runners look untouched. I herd they bad about being worked on alot. You guys have been alot of help!!!
