Here's some more questions for ya:
What kind of '74 Ford?
Is the engine original to the vehicle?
Heads This site says the heads are from a 360 or 390 FE with hardened valve seats.
That would also mean it must be an FE engine.
You'll have to measure the stroke to determine which it is.

Also the "D2" suggests '72 for the year of the heads but I don't know if they still used the same number for other years.

Hi, and Thanks for the help.
The engine is in a 1974 F-100 truck. I believe it is original to the truck.
The title and door vins match, but on the tag found behind the engine
the 5th letter changes from an R to a P. Other numbers on the tag are as follows :

F10YPTO4658 26-116
YX 133 BDY 4 WDE
MN DLX RPO CUS
C X E ? J MID AFT

( between the E and the J ( where the ? is )
in the last line there is a cutout that resembles a 6 )
It is also a side oiler.
Do you have any idea what D2TE-AA stand for ?
From what I've read the AA stands for PI side oiler.
Does that sound right ? Thanks for your help.

Hey Beaur, to be honest I'm not sure what the other
numbers/letters mean but I can tell you where to find out.
Go to Ford Truck Enthusiasts forum 1973 - 1979
F-100 & Larger F-Series Trucks - Ford Truck Enthusiasts Forums.
Register with a username/password like here and go to the
'73-79 section of the forum.
Post your VIN, etc and those guys will help you with all
kinds of info.
Ford trucks is all they do so there's a lot of good
info for ya there.

And here I am, anybody have any ideas what these numbers and letters mean ? Thank you.

 

Casting number D2TE-AA heads have hardened valve seats, do not have threaded holes for T/E (Thermactor Emission-smog pump) manifolds. 1972/74 360/390, 1975/76 360/390 without T/E.

Since all FE's were cast as 352's, some have the 352 foundry mark cast onto the blocks. This does not mean the engine blocks are 352's, quite the contrary. 352 cancelled at the end of the 1967 model run.

1972/76 FE blocks usually have a reversed stamped 105 foundry mark.

1968/76 360/390 share the same block, the bore is the same (4.05"). The stroke is different: 360 = 3.50" / 390 = 3.78."

The engine code is the 4th digit of the VIN.

1965/76 F100/350 FE: 1965: D = 352 2V // 1966/67: Y = 352 2V // 1968/76: H = 390 2V // 1968/76: Y = 360 2V // 1974/76: M = 390 4V.

Im sure the block you are talking about is not an FE but a FT 361/391 105 Block. You can also read this post here:
http://www.fordification.com/forum/v...php?f=3&t=1226

 

Any idea what the -AA means ?

 

I believe that AA means that the basic part (cylinder head) has been changed 27 times (A through Z plus one for A = 27). ND will know for sure.

 

It's not your fault because you are unaware..

This is HORRIBLE CRAP INFO! One error and/or omission after another. Do not believe any of it, it's from the awful POS Red Book not from any Ford source (parts catalog, shop manual, whatever).

This book was first published in the 1970's. It was crap info then and it's crap now.

I trolled thru the casting numbers, there are engines listed for the 1960's, that FoMoCo didn't offer until the mid 1970's. There are engines listed in the late 1970's that FoMoCo cancelled several years prior.

Ridiculous!

Fordification also used this POS book for their 1973/79 VIN/Warranty Plate decode info. They claim the info is from the '73/79 Ford Light Truck Parts Catalog, but it ain't.

Anyone that has the Ford catalog can look at Fordifications charts, and they'll see that not one chart matches! And since they used this POS book, much of the decode info is WRONG!

 

Maybe so, I just know its an FT block. here is another link to ponder......

Big block ford 390/391 - Hot Rod Forum : Hotrodders Bulletin Board

 

Some info is right and some is off. The FT blocks needs a smaller bushing in the lower dizzy shaft guild hole to hold it in place with the cam dissy/gears mates. My motor came out of a 1974 pickup had a 390 mirror 105 block motor. The FT has a larger crank snout with a larger hole in the front cover. And I heard some had a steel front cover but never saw one..
So the block can be what ever until it's built into a FE Or FT with the inner and outer hard parts.. I'd say Fe..
orich

 

Orich, the only reason I'm saying its an FT engine is because he says it is a side oiler. Never saw an FE with a side oiler except a 427 side oiler. However, I have seen an engine from an F600, with a 391 that had a side oiler and an external oil cooler. A friend of my dads got it and put it in a 67 fairlane and it ended up being a piece of crap, LOL.
Like above as numberdummy posted, it should be an FE 360.....but a side oiler?

 

1968/78 330 2V M/D FT uses the 1968/76 360 crankshaft (C8TZ-6303-A). 330 H/D FT uses the same crank as a 361 FT. 391 FT crank is 391 only.

 

Cool.....what about the side oiler they mentioned in the first post. Just curious.

 

Does the OP know what a side oiler is? No, obviously not! Post 1, 5th paragraph:
It does not, AA suffix refers to the design of the head. Where people come up with crap info like this, I haven't a clue.

The 'tag' mentioned in the 4th paragraph "found behind the engine" is the buck tag riveted to the firewall.

Codes on buck tags were used by assembly line workers to assure the correct parts that matched the build sheet were installed on the vehicle.

OP claims that based on the VIN (F10YPT04658) on this tag:
No, it is not: F10 = F100 2WD Pickup / Y = 360 2V / P = Twin Cities MN Assembly Plant / T04658 = 1974 / Same 360 Y VIN engine code used 1968/76.

And: There is no reference in any Ford parts catalog for the PI (so-called Police Interceptor) abbreviation. The correct abbreviation is P/C = Police Cruiser.

How many 1963/68 P/C's came with expensive optional 427 side oilers? There is no 1963/66 info available, the 1967/68 info would be available from matriauto.com.

 

I know the AA doesnt stand for side oiler..........Some people huh??? Thats why I was thinking its an FT block because thats the only other "side oiler" I have ever saw other than the 427 side oiler.

As for the police interceptor, Ford and Mercury made them. A 330 H.P. version, also with solid lifters, was offered for law enforcement (police interceptor) although it could also be ordered by the public.
Here's what the 63 Ford Police Cars and Emergency Vehicles sales brochure says:

330-HP Police Interceptor 4-V/ 390 V-8
390-cu. in. displ.; 4.05" bore x 3.78" stroke; 10.5 to 1 comp. ratio; premium fuel; 2-stage, 4-venturi carburetor with automatic choke; 6-qt, oil capacity with filter change; copper-lead main and connecting rod bearings; dual exhaust. Special features include high-lift camshaft, solid tappets; high-performance valve springs with solid retainers and internal damping springs; free breathing air cleaner, forged alloy exhaust valves with chrome stems; low-restriction headed-type exhaust manifolds; plus other hi-speed and long life features.
HP 330@5000rpm
Torque 427@3200rpm
Compression 10.5 to 1
Available with 3-speed, 4-speed, 3-speed overdrive or Interceptor Cruise-O-Matic.

This 390 engine, like the 428 CJ engines, all came with higher reciprocating internal parts from the factory. The PI engine came with a square "police interceptor" sticker on the valve covers. I "think" the police interceptor engine code is "P", in 1964 anyway. I have a high performance engine code book somewhere but I cant find it right now, and now I have to go to work......so I Will have to dig it up later.

 

I really appreciate all the info. Very confusing tho. Please let me know id you come up with anything else. Thank you.

 

Found this tidbit on e-how, but it really doesn't help, again. Just says that the single capitol letters identify high preformance. Still stuck on the AA

Look for any additional number that follows the primary four-number string. They typically appear as single capital letters, which identify highperformance models; performance high, medium and low risers; sport models, or thermactor-air pump engines, made of aluminum.
