I have purchased a 1975 f100 with a 302 motor. The motor is not original (so I have been told). I powerwashed the engine today (it is installed in the truck). I then laid on my back an looked to the starter. Just to the right I saw EOEA and below it I saw D3C. Are these numbers indicitave that it is is a 1980 engine from a fairlane or Torino? and if so what are the remaining letters/numbers. Please help. I am having a hard time looking behind the engine as the firewall is obvoiusly there. I have read this is where to look for full numbers.

 

This might help:

Classic Mustang Part Number Decoding Guide

 

Thanks for the reply. I can do the decoding from the chart provided. My question is if these letters and numbers found near the starter are what I need?

 

Fairlanes and Torinos were no more by 1980.

Are the characters above cast on the block or on the starter?.. it's not clear to me.

Using the decoder provided, it's either a Pinto or COE truck. However, Pintos never came with a V8 so by deduction it would appear to be a truck-sourced 302.

 

Fairlanes were long gone by '80, and the last year for a Torino was '76.

There are pics here of an earlier block with the casting numbers by the starter as you have found, so I think you are on the right track there:

C5AE-6015-E

This shows the vehicle line of E to be something a 302 never came in:

It also explains date codes, and the date code format you list does not look right.

Are you trying to figure out stuff like water pumps or other parts?

ON EDIT: HIO beat me to it...but afaik, no COE truck ever came with a "Windsor" 302.

 

The numbers I found were above the starter, not on the starter. they were not in a long line. I had the EOEA then below I have D3C.

 

I need to know what it is because the previous owner put the oil pan drain plug in and stripped it, now I need a new pan, but dint know what my motor is.

 

Why not pull the pan and weld on a new bung? Cheaper than a new pan.

... unless ya pull one from the salvage yard. Keep in mind whether it's a front or rear sump if ya have to ask for one.

I've heard of guys using JB weld to re-tap munged threads. Maybe worth a try?

 

I would do some investigation using a parts store web site (Rock Auto is good for this).

The E0 says 1980s, you can look up the part numbers to various cars & trucks with the 302 engine and see if they're the same or not.

You're going to want a rear-sump pan (to my knowledge, anyhow, although I'll be the first to admit my knowledge of 70s stuff is far from acute) which came only on trucks, I don't think any cars had this. Somebody will certainly correct me if I'm wrong.

 

If it's just a stripped-out plug, there are oversize plugs available.

As HIO said, could also take it off and weld on a bung.

 

The Casting number you want is actually up in behind the starter, and is nearly impossible to see with the starter installed a good number of times... It is pretty much litterally behind the starter on a lip where the block kinda curls...

I have a feeling this is the same link as posted before...
Decoding Ford casting part numbers

 

Yes, this is exaclty where I see the numbers/letters. It is so impossible, I cant even get a picture of it. So knowing what you say, I think I have found it.

Thanks Guys

 

No such thing as a block casting number prefix (or ID engineering number prefix) of EOEA, the OP reversed the last two letters, the 2nd digit is a zero, not the letter O.
'
E0AE block casting number prefix applies to 302: LTD/Mercury Grand Marquis/Thunderbird/Cougar/Lincoln Town Car/Continental Mark VI.

D3C = Block cast the 3rd week (C) of April (D) 1983 (3).

Fairlane history after 1971, Torino nameplate replaced by LTD II in 1977, a confusing name the IDIOTS at FoMoCo came up with. Thankfully it passed away after 1979.

 

'just going by what the OP posted. Who better than the witness? Apparently, not this one. ZOIKS!... 'hope the OP don't work on airliners.

Garbage in=garbage out

 

I know that, I quoted your post so you would know and the death dates of Fairlane/Torino's.

What surprises me is...that Chris (ctubutis) didn't know this EOEA/E0AE jazz since he has a 1980/89 truck parts catalog.

And, since FoMoCo is in-famous for replacing/updating 10's of 1000's of part numbers EVERY YEAR, people should not go by casting, ID engineering and part number prefixes to ID what vehicles/years the part fits.

If you needed a 1/2" -20 lug nut for your 1932 Ford, 1975 F100 and etc., any of the following p/n's would be correct: B-1012, B-1012-A, C0AZ-1012-A, C9AZ-1012-A, E6DZ-1012-A, E8TZ-1012-A
