Does this look original to you?

This is an original, not repro used Ford "FOMOCO" exhaust manifold from a 1966 Ford Mustang with 200 CID Six Cylinder engine. It will fit 144, 170, 200, and 250 CID six cylinder engines. The part number is: C3DE-8430-A. It's in pretty good condition for a 42 year old. I can see no pitting, cracking nor leaking. The "FoMoCo" logo is nicely prominent. I did a pencil rubbing. Looks like "10"; "12-12-88"; and a large "S" embossed on top, between #5 & 6. "10" embossed on the bottom between #1 & 2.

I thought an original exhaust manifold would have a date code on it? But it does have a ford logo.

Yes, they should have a date code.

The date code on my 66 is on the left side, opposite the FoMoCo logo. Hope this helps!

I would say that one is a service replacement
part from Ford and the date code is 12-12-88.
I have a Ford service replacement that has 9-13-94
for a date code. It is cast into the top of the manifold
between where the carb goes and the firewall.

Would this be acceptable on a concours car or should i keep looking for an original. It at least has a FOMOCO logo, thats better then the repros can do. It seems nice originals are harder to come by then i first thought.

I guess it depends on what extreme you want to go to.
If your car has all correct date coded fenders, hood,
etc. then I would think that you want the manifold to be
so as well. Charles can answer on if the judges would
deduct points for the date code, maybe as long as it has
the FoMoCo stamp your ok.

Those are not the easiest items to find in used cond..........without cracks. It's a later piece but it appears to be a better risk than an old one. Ame assuming you plan to drive the car from time to time.

Just a correction, I think that the part number is: C3DE-9430-A, not C3DE-8430-A as you mention above.

Please correct me if I'm wrong..

I've seen many of the originals crack...so they were prone to over time with that amount of heat +35 plus years/age.. I managed to score a clean original in a swap deal, and It went with my mustang hardtop when I sold it.. The original that it replaced was in the worse condition that I've ever seen a manifold. It was hurtin'! It was welded 3 times! I still have the digital pics somewhere. My 200 cid convertible had a brand new repro on it when I bought it...so at least I don't have to worry about it being bad...but it does not have the FOMOCO logo...just the Ford C3DE-9430-A part number molded into it. However, If I ever come across a clean original FOMOCO again....Out it comes...

I think you are right. I think the guy mistook the 9 for an 8. If you look at the picture you can see how it may not be easy to tell.
My original wasnt cracked it is just so badly pitted the part numbers aren't even leadgeable. and were it mates with the head is also badly pitted to the point were it would take a lot of grinding to make it sit well. I only found one machine shop around here that still grinds exhaust manifolds. The guy told me these are one of the worst to grind since they are so long.

As long as it matches the factory original as far as shape, fit and finish it will be fine in concours. Appropriate date codes are only required in Thoroughbred/ Div 1 cars
