small block manifold casting

I am trying to determine what engine and manifold I have. The manifold casting is confusing me. It appears to read: C3OE-. Everything I have found says this is an engine code, not a manifold code. Am I reading it wrong?

Have you seen this link... Classic Mustang Part Number Decoding Guide

Ford uses the same basic numbering code for All kinds of parts...

For your review.

C3OE will appear on many parts.

Thanks again. This is the rest of the engine. It came with a new purchase. Somewhere along the line, someone stuck a set of 302 valve covers on it.

What is visible is interesting, it would be neat to see more pictures, especially with the air cleaner / scoop removed.
Someone has modified the road draft tube to go to the carb, presumably via a PCV valve.
The oil fill tube is also characteristic of an early engine, a 260 or a 289.
The alternator installation looks pretty hokey.

It's a 63 engine. That much I am reasonably certain of. 260 or 289 is yet to be determined. It's in and has been in a 1935 Ford tudor slant back sedan, for at least 50 years. Hokey is not a word I would use to classify the alt hook up. But, it works and is solid. I am guessing the road draft tube was rerouted in an attempt to get it past state inspection. It is an unusual find, for sure. It looks very much like the original radiator. I am going to try to have it road worthy and inspected by spring, so I can hit some of the local shows. Cleaning up under the hood and getting rid of the scoop will be a huge part of it.

NICE SWEET 35 man
that alt hook up may look Hokey but thats how we used to turn a external regulator gm into a 1 wire, down side is they always put out 14.2 and tend to cook the battery fuild out,

i'm building this right now, that motor is a real K code 289,

Now that is looking good Charlie. Did you stay with the stock bore on the K code?

That's a nice car!
I've had a couple 260s and a 289, the 260 is a very good motor, the 289 is 11% better!
It's the alternator bracketry that I was commenting on, not the wiring.

The cylinder block casting number, which will tell what the engine size is, is located above the starter motor, you might be able to see it from under the car.

luckily the bore cleaned up almost standard it's only 002 out with a simple hone job ,crank stayed standard/standard. we did ditch the solid lifter cam for a hydro of the same specs. the motor is one of the 306hp shelbys not the normal 271 hp k code
as to the ops motor,i'm guessing it's a 260 counting the bell housing bolts would help if 5 it's a 221 or 260 if 6 it's a 289

Unfortunately it's not quite that easy. In 63, (I know this engine, or at least the intake, is a 63), the 260 and 289 both had a 5 bolt bell housing. The 6 bolt came out along with the 64 cars. Some, but not many, 63 289s got the 6 bolt.

Yeah, I haven't been under it yet. Too cold for an old man to be crawling around on a cement floor!

I may have to get a proper spacer to replace that piece of black pipe. Then again, there is a value in the "curiosity department"!

289 engines for 1963 and 1964 were 5 bolt bellhousing, except that Mustangs which really should have been sold as '64 models were called '65, causing endless confusion.
So early "65" Mustangs have 5 bolt 260s or 289s.
