A 1974 Falcon Didn't Exist?? D4DE Engine Casting Code

I just bought a 302 engine that was pulled recently from a 1977 or 79 F150 but the engine Casting Number says D4DE-6015-AA built on July 17, 1974.

The odd thing is, this engine is supposed to be from a Falcon which was disconntinued in 1969-70. Anyone have any history for me?

My Guess is it's a Maverick Engine...

Where've you been? Of course Ford made Falcons in 1974. Here's a couple of photos '74 Falcon GT!

Actually, the American Falcon was phased out in 1970. However, the Australian Falcon continued to be in production and is still manufactured as of today, branded as the Ford FG Falcon.
Not that the above history helps you, I don't think that the Australian Falcons even had a 302 in '74.

I went ahead and broke down the number you provided:

D4DE-6015-AA

D4=1974
D=Falcon (60-69)...so I believe a Maverick may be correct
E= Engine

6015=Engine ID tag

AA=design change

So, you have a 1974 302, most likely from a Maverick

I literally just picked up the engine a few hours ago...

I'm not sayin Wiki is always right, but it doesn't say they were built in 1974. At the bottom under External Links there is a ford vehicle time line, which also shows the Falcon stopping production in 1970ish. That car looks like a Maverick...? They're virtually the same car I believe? I don't know much about those fords. I just bought my '65 Mustang Coup last summer.

I was just joshin' ya! I flipped the photo to make it look like a left had drive car.

That is a 1974 Australian Ford Falcon GT. I think Ford Australia is still building Falcons down under but I have no idea if they used casting numbers like Ford USA.

Thanks for the decode, it's exactly what I got, which is good
I just read too that the Falcon continued in Austrailia.
I also read it may have come from a Granada (spelling).

I'm looking to rebuild and drop into my '65 mustang coupe eventually. I'm a newbie to engine rebuilds, so I'm looking forward to starting this winter. I need to find the correct book though...I heard the deck on this block may be thicker...we'll see once I get some more research done.

No worries 67ragtopstang, it's a sweet looking ride though. I think they used a falcon in Mad Max...?

You are correct about the deck height on the 302. The 1973-'76 302 deck height is 8.229". In all the other years, such as 1965, it is 8.206".

Thanks again!
I'll have to see how crazy a rebuild I want to do and what condition the block is in once I rip it apart...hopefully it's in good condition!

I think you're right about Mad Max's car. I like the looks of this Falcon, but I would have put chrome bumpers on it.

You are reading way too much into that 'D' in the casting number. There was never a 289 block in a Mustang with the letter 'Z' in the casting number. They used C3, C4, C5, C6 and C8 with either AE or OE. That does NOT mean there were no Mustang 289 engines nor that they didn't have one in 67. It only means that the 289 was never designed as a Mustang part. It (HiPo included) was designed to hot rod a Fairlane and later as a small V8 for the Galaxie . (I drove one of the 289, '66 Galaxies for 4 years). It was used as a Mustang engine but designed for something else.

Besides 'D' from 70-74 meant Maverick, 75-82 Granada and from 83 on it meant an LTD.

I have no record of the numbers they used in the 70s but that block (Ford block = part number 6015) could conceptually have been in most anything Ford built at the time. There is surely someone who knows what numbers were used in 74 and a few years beyond but don't be surprised if vehicles other than Maverick are on the list for that block - like F150 pickup truck.

I'm not sure I follow the first paragraph you wrote, but the 3rd digit (a 'D') means it's from a Falcon (according to decoder websites), but it probably should have been more specific like you're saying in your third paragraph. It was pulled from a '77 or '79 F150, so that's about as much as I know about the engine. Its interesting to say the least.

Actually my '65 D-Code mustang block says it's for a Fairlane, but the build date is within 2 weeks of the car itself, so it's more than likely the original.

If that is what they are telling you then the decoder sites are telling you wrong. They are trying to give you a super simple explanation which causes repeated problems.

What I am telling you is what you see on your own car. The 3rd letter does NOT mean that part was ONLY used on that line of car. Ford regularly used the same parts in many cars and they saw no reason to number them differently for each model. Unless, of course, there was some difference in the part for that car. As long as the same block worked for everyone, it had the same number for everyone.

Your D-code engine was a low compression 289 4V only used in the Mustang which became the A-code when they upped the compression. Even though only Mustang used that engine the letter was still an 'O'. There was NEVER a C*Z* engine block casting number for a 289 of any type. Those C4OE-6015-C & F block casting numbers were used to build not only the Mustang D-code but the K-code HiPo engines which went into Fairlanes, earlier Mustangs and by special order in Comets. ANY '64 289 blocks were the same number in Full-size, Fairlane, Comet & Mustang; they all used the letter 'O'.

That makes sense.

When I changed my water pump I had to use the K-code edelbrock water pump b/c my timing chain cover was different from a normal '65 (i.e. no backing plate was needed).
