460 SCJ factory engine

I'm new to this web site not new to rodding. I'm hoping one of your members can help me out. About 30 years ago I bought an engine that came out of a 73 mercury police car( not sure if it's Kansas or Missouri highway patrol) when i bought this engine the man I bought it from showed me an article in one the of ford magazine ( ford power, fords and mustangs i can't remember) talked about this engine. it was 11.3:1 compression, .510 lift - 300deg. duration cam, cobra jet heads, and an external oil cooler. I have been called a liar, told I have been scammed,
Ford never built it. With the exception of the article I was shown and the fact that the man was a personal friend for years prior to this I might shut up and just enjoy my engine. If someone has ever heard of this engine or could shed any light on it or any information would be gratefully accepted.

You will need to get the numbers off the various engine parts to be able to really tell what you have. Find the numbers on the heads, intake, block and any other engine parts that have numbers on them. As far as I am aware Ford never made a 460 SCJ for production. Or someone could have pieced one together. You could very well have a Police Interceptor 429/460. Get those numbers and then we'll see what you have. Does it have solid lifters? what exhaust manifolds (if any) does it have??? Let us know.

it did have solid lifters I went with hydraulic after rebuild.I'll get the #'s and get back with you.

What you have described sounds like a 429SCJ, but without numbers it's hard to say. When it was rebuilt do you know what numbers were on the crank? A 4U would be a 429 crank, a 2Y or 3Y would be a 460. Solid lifters were standard on a 429 SCJ as well as fully adjustable valve train. Also if it was a true SCJ it would have had 4 bolt mains, although there were other 429's that had them late build CJ's and 72 Police 429's. Block should be a D0VE, Heads should be D00R, the intake if it were a SCJ would have been a square bore for a Holley carb, CJ's had Quadrajets. Do you know the part number of the pistons you put in it when you rebuilt it??? Was it rebuilt once before you got it? Let us know.

no it was all stock before the rebuild. It had the d dished pistons. the intake is a square bore.

it is a 460 pistons were custom made when i rebuilt. very expensive.

Is your friend still around?
Dose he still have the article?

yes, I haven't talked to him for a while but I'm am going to look him up and see if he still has it or remembers.

Well that's a start but, with dished pistons it didn't have 11.3 to 1 compression. Even with CJ heads the compression would be around 9 to 1. With Police Interceptor heads it would be around 8 to 1. If it was a CJ/SCJ or Police engine it would have had flat top pistons with 1 valve relief. Get those numbers and we'll figure it out. You don't have the old cam do you?? The intake should have D00R on it also. there were other square bore intakes that weren't SCJ's. With out the numbers it sounds like someone put a SCJ top end on a 73 460 block. Back then the only parts for 429/460's were from Ford.

Yes I still have the original cam and intake.

Check the cam if it is a factory SCJ cam it will have a upside down "B" with a "J" stamped on it near the distributor gear at the front of the cam. A CJ cam will also have this mark but they were hyd. lifter. If not check for any other numbers on it to see if they can be traced. Get those numbers!!

there is a B on the cam couldn't find the J. The intake is a D4VE.

sounds like a conglomeration of parts thrown together and sold to you as a bill of goods...I can't find anywhere in any archives where ford made a 460 SCJ just 429 CJ's and SCJ's

Okay so it could be a SCJ cam...But the intake is from a 74 460 not a high performance piece at all. Get the numbers off the heads and block. Does the cam have 2 grooves around the dist. gear?

Ford did sell a 460 kit from their old Ford performance parts program that had new pistons and a 460 crank, but even those pistons were flat top. It sounds like the Coug is right just a bunch of parts. Still get the head and block numbers.

Yeah, I will. To be honest I'm more confused now then before. What I was told was the merc it came out of was a 73 highway patrol car. Some old lady bought it ( no joke) and complained about the mileage it got. The guy at the shop swapped her straight across for a 302. He sold it to my friend who was going to run in his super gas car, but he opted for the SVO small block. Which is when I bought it from him 28-30 years ago.It sat around for ever cuz I was building it with the grocery money. Just recently got it running. But I will get the #'s.

It very well could have been a 460 Police engine, That someone put a SCJ cam in, but a 460 PI engine wasn't that much different from a regular 460 in 73. Also No police department would have had a engine with solid lifters, think of the maintenance. The "good" PI engine was the 72 429. Get those numbers!

Block D1VE-80
Heads D20E-A

Block standard 429-460...Heads are 72 Police Interceptor a really nice find. But sadly not any where near a 460 SCJ. So it seems that the Coug was right...Just a bunch of parts put together, not anywhere near a factory engine. Depends on what you paid for it 30 years ago. Maybe the guy you bought it off of didn't know any better and went by what he was told. Sorry for the kinda bad news. Good luck.

admittedly none of the three of us were 460 experts. well at least I don't feel to bad considering I threw some other go fast parts in it. So what is the difference between the scj heads and the PI heads? I paid $500.00 for engine. The motor screams I had a 428 PI and this runs alot harder then it did.

the D2OE-ab heads are smaller in port size but in the right hands can scream if you have $500 in the whole combo you are ahead those heads go for alot more than that.....seems the intake is limiting everything else it is STD 460 intake not PI or SCJ

would just like to thank everyone for the information and their input. At least I know I got. Thanks again.

My family has had a few 1973 460 police interceptor engines. They are unique. They do have the D20E-AB heads, but also have unique pistons. They are TRW forged pistons with one large valve relief and a D shaped dish. They also have CJ type connecting rods. Also, an oil cooler and high flow exhaust manifolds, very similar to CJ/SCJ on a 71 mustang.

The parts they did NOT have, which a 1972 429 police intercepter had, was a large port intake manifold and aluminum finned valve covers.

The oil cooler adapter used on both the 429 and 460 PI engines was the same one that is used on 71 Mustangs with a 429 SCJ.

Yes they had the valve relief and the rods were the CJ type. After the discussion here I remembered that thats what the atricle was about that it was a PI 460. Had just been a while and do truely appriciate everyones input and help with this.

Sounds like you have a PI engine.

Someone probably swapped in the solid cam, but there is a slim chance ford could have put it in.... Weird stuff does show up from time to time.

Same goes with police fleet maintainence, you never know what they would have done to it to fix it or make it go faster for Rosco P. Coaltrain......
