Fella's I have a couple questions regarding offerings of the D20E heads. Being D2 did they only come on 72's or were offered later on something.

1. What exact year and type vehicles were they offered on ?

2. If they came in a Ranchero is it classified/insured as a car or truck ?

It is a torino frame that they came on correct ?

Just so you know it is for a rule clarification that states truck line engine only. I am neither for or against just want to help clarify for rule committee in a stock type mudrace class. A racer claims they were an option on a ranchero and a camper special.

Thanks for any info,

Mark

Police cars only ('72-maybe some '73). But what kind of cars/trucks could a Police Department order? I have never seen them on a factory version of a car or truck if it wasn't a police car.

either Paul or Scotty had listed another engineering number or 2 for them. It was D3##..AE or AZ or something like that. What years they were available for is beyond me.

I know they were still available in 74 because my first 460 came out of a 1974 Mercury Montery with a police interceptor. I believe the car was a detectives car because it had no markings on the exterior that it was a police car but said police interceptor everywhere on the interior and also at the bottom of the emissions sticker on the valvecover. It had points distributor and a holley 1847 on it. I thought that was one ugly car at the time but looking back maybe it was me being young.

If my understanding is correct the D2OE police head ONLY came out after the switch from the 429 to the 460 police engine. 429 police was really the same engine as the 429 CJ, 460 police was not. Remember D2VE heads are not the police head, only D2OE this has lead to a lot of confusion for junkyard shoppers. My impression is that the D2OE head is not particularly common and probably less common than the DOOE-R CJ/SCJ casting.

Or is 1972 the year they switched to using the 460 as the PI engine? I don't know when that happened for sure...

That makes sense then, after 71 the 429 PI was actually it's own engine and not a 429CJ. Then sometime after 72 the PI engine became the 460 and that was probably after the '73 model year. I've seen a lot of old Fords in the junkyard but I can't say that I've ever seen one that was a police package. Most all of those must have been long gone by the late '80's.

A Ranchero is classified as a truck, not a passenger car.

I don't know all the details from year-to-year but will do my best to be as accurate as possible.
  • From somewhere in the 1960's and up to/including the 1970 model year, the FoMoCo PI engines were FE's, typically the 428PI (which is of the FE Family, not to be confused with the 429PI, which is of the 385 Series Family).
  • In 1971, the 429PI debuted. It was basically a 429SCJ engine with D0OE-R heads, 4-bolt D0VE-A block and forged flat top pistons, etc. The SCJ intake may have had the spreadbore carb pad, though (I'm not sure)
  • In 1972, the dedicated 429PI engine was released. This engine usually had the 4-bolt D0VE-A block, D2OE-AB Police Interceptor heads, flat top forged pistons, and an SCJ-style intake with a spreadbore carb pad.
  • 1973 brought the 460PI. It had TRW "D"-shaped dish pistons and (I think) the D2OE-AB PI heads. Not sure what it had for a block and intake.
  • 1974 was the 460PI. Here is where I don't know what's going on. Somewhere around this time or perhaps in 1975, they went to the D3VE-A2A passenger car head.

My experience is pretty much the same as Paul states. I would like to add one small detail though.
The '71 to '73 police intake was a CJ style intake with a Ford spread-bore pattern. Still have a '71 intake somewhere. Also have some pistons from a '72, forged flats with a D1OE-6110-HA # on them.
Some might confuse this intake with the '70 CJ with a Rochester pattern.

That's interesting to hear that the early 429 police used the CJ intake but didn't use the Quadrajet carburetor and instead used the Motorcraft. I wonder why they did that change? Possibly emissions?

Paul, only a few had the 4 bolt blocks. I saw several of these engine in the early '80s with the oil pan removed.....only one had 4 bolt caps.

To add to this. More likely to find a 4bolt block in the '71s. Over half of the engines in '71s I bought had that block . I have found 1 in the '72s, was a 429 w/D2OE heads/CJ type rods. I think you could say, early engines had a better chance of having them.

Not sure why. Still have a carb off one too. Worked OK for a while. Let it sit too long in the garage though. Needs reworked to use it.
I want to add, the cars I am talking about are all from southern Indiana. Some were in Indianapolis junk yards and some from northern KY. It could be different for other states. Not everyone used the same requirements for their cars.

Paul my 74 PI 460 had the D2OE-AB heads on it yet but it was points ignition and was told that being a 74 shoulda had electronic :confused:. Had some people tell me it must have been an early 74 where they were still using leftovers from 73.

Yes the Ranchero is classified as a truck. All the license plates on them here in Texas say "Texas Truck". You also have to pay the truck rate registration fee when you get a new sticker. I always found that funny as you dont with a station wagon or large 4-door sedan which is usually the same platform. What the hell is this world coming too?
