So while I have my engine out and cleaned I now see Firing Order numbers cast in the intake manifold and I see Cylinder numbers next to the associated piston. Are there any numbers on this block that will tell me anything about what type of engine it is, when it was cast, and that kind of stuff?

 

If the engine is orginial to the truck; your vin number will enable you to determine the engine size, on the side of the block near / above the starter is usually your casi ng block number. It should read something like D0AE6016C something of that effect.
Ford part number started back in the 50's; the 1st digit is the 10 year era increment ( like A=40's, B=50's, C=60's etc, the second digit is the year with that 10 year increment (D0= 1970 model. The 3rd digit is type of vehicle A= full size car, T= truck. The 4th digit indicates wheither a engine part or chassis, E= engine; C = chassis.
I hope this helps; to determine wheither its a 302 or 289 etc is alittle more challenging.
The firing order will also weed out engine types as well.

The intake manifold has a little tag looking thing that is cast into it that looks like it was screwed on, is far as we can tell it is 0022 or 0D22. According to the code keys this is probably 0D22 for April 22nd 1970, since there is no code key for a 0 as the second number for any of the months. As for the firing order is says on top of the manifold: FIRING ORDER 1 5 4 2 6 3 7 8.

There is also another number right under the 0D22, C8AE - 9425 which from what I can tell is 1968, Galaxie, Engine Engineering Dept. No revisions.

And now my son calls me up and tells me that there are the Letters C8AE-H in between the spark plugs. According to the info on the web that might mean that this is a 427?!?!?

There are a couple of other numbers or letters that we cannot find reference to. Right Above the 0D22 there is the number 17 and then on the sides of the block there are the letters DIF ? Can't seem to find what these mean.

 

You need the engine forum not the truck forum.

The block numbers are locate just above the starter.

Those casting numbers 17 and DIF are only Ford plant Identification codes.

Engineering numbers are DESIGN NUmbers

The suffix is the change up number re: part design.

as you can see that part was designed for a 68 Large ford car (Galaxie/LTD)

was cast in April of 1970 for what ever vehicle and the part has gone through 7 changes up to 1970.

Probably the emissions outlets and things like that.

I would be pleased to continue if you ask a mod to move this to the corresponding Engine forum ..the FE forum.


427 ?

 

Engine information can go either in the engine section, or the vehicle section that covers that engine. Truckboy, its okay... you're posting in the right section.

(If something is in the wrong section, the FTE staff decides that. )

 

Look at the coil where it mounts to the manifold, there should be a metal tag attached by one of the coil mounting bolts (if it hasn't been removed over the years) and on that tag is much of the pertinant info you want. For a very good breakdown of casting numbers, look here:

Thanks everyone! Yea my coil is now an Accel coil and is bolted to the Firewall at the back of my engine compartment. I did find a tag on the top of the manifold that pretty much tells me that it is a 390 but the tag that is similar to that on the Heads, next to the spark plugs points to a 427. However the build up of concensus is the numbers 63 and 352 below that number on the front of the block above the oil filter, the fact that I have two bolt engine mounts, and the sides of the piston counter weights are beveled all point to a 390. I have not taken the dowl displacement measurement but I will later.

As usual THANK YOU EVERYONE! This has got to be the greatest on-line forum community that I have ever dealt with. I love the modern internet world! I can't imagine slugging through this without this site...

 

Those C8AE-H heads were used on the 1968 ...360,390,428 with thermactor.

Aside from being classed as HIgh Performance ...They are nothing special and definitely not a 427.

 

Sometimes...not always, you can ID the engine IF the dizzy is original...look on the base of the dizzy, below the rim of the cap. There will be a number code there like: C8AF-12127-F.

Is the dizzy a dual point distributor? Ford p/n: C0AZ-12127-L. Marked >> C5AF-12127-E.

 

Nope, single point and I don't think it is the original dizzy since I was able to find a Mallory label on it.

 

You have to IDent the crank or do the stroke measurement to know for sure.

 

I am going to be replacing my main bearings so where on the crank does it tell me what I need to know? or is it a measurement thing?

 

The Number is stamped on a journal.

I'll get you the numbers to look for.

EDIT:

360 = 2T,2TA

390 = 2U,3U,2UA

 

You can also measure the stroke with the engine still assembled and in the truck. What I did to verify that mine actually was a 360 and not a 390 was to pull a spark plug and insert a wooden dowel into the spark plug hole till it rested on top of the piston, then turn the crank by hand while steadying the dowel and feeling for BTC. At that point, make a mark on the dowel at some reference point (like the top of the spark plug threads) and then turn the crank again which will push the dowel back up, till you find TDC (either by feel, or with the timing pointer if you're doing the #1 cylinder). Make a new mark using the same reference point as before, pull the dowel and measure the distance between the marks. This should be very close to your actual stroke. If it's a 360 you should measure 3.5 inches, if it's a 390 it'll be 3.784, which is a bit over 3-3/4".
