Default 428 Police Interceptor Motor questions

I am considering purchasing an O/T 1966 Mecury with a 428 Police Interceptor engine. I know nothing about these FE motors. Were these good motors for Ford? Are they worth playing with? Are speed parts readily available for these?

Well it was built to chase down hot rodders in that whale of a mercury if that answers your question.

Great engine and plenty of aftermarket support for anything you want to do.
Just do a basic search for 'ford fe engines' and start trolling web sites.

Are you sure it is a 428 PI? In 1966 the full size Mercurys also came with a 410 or a standard 428. If the Mercury you are looking at still has its original engine, the cars serial number tells what engine it came with. Do some research on the internet.

The CJ engine was not the same as the 428 PI. The CJ had a better block and heads.

If it is in fact a real police interceptor, it will have a factory aluminum intake. It is the basis for a great engine. Even stock a PI is a good engine with a lot of upgrades over the basic 428.

Don't listen to these other guys. That thing isn't worth a damn. Your best bet is to box it up and send it to me so I can dispose of it properly.

365 Hp and 459 ft-lbs of torque from the factory, yea, they do all right.

I'm not a Ford person, BUT, a friend had one, a 428 or 429 Police Interceptor (can't remember exactly) in a Ford pickup truck with an automatic, aluminum intake and Holley carb, and headers. I wanted that truck, it was a sleeper, but he just used it to haul stuff with. He had bought it that way. He wound up selling it without even asking me, and when I asked him why, he said he did'nt think I'd be interested in it since I'm a Chevrolet guy. And this was after I let him store his 39 Plymouth Coupe, with SBC and GM powertrain, for about a year and a half, in my garage, free of charge! Like I said, I'm not a Ford guy, but if it's a big motor, "it's a big motor"!!! (like Chris from "Sons' of Guns" would say). So, I'd get it. Butch/56sedandelivery.

I knew a guy who claimed he put a 428 PI in place of a 391 in a ten wheeled dump. He claimed he could haul potatoes faster than anyone in the whole valley.

Absolutely! X2. Just don't expect it to be anything like a high-reving, huge bore & short stroke, high nickle content, powerhouse, the 427 is.

I have a '68 PI from a CT State Police Galaxie in my '73 F-250 High-Boy.
Lots of torque, has been trouble free since the early 80s. Took me to Ft Benning and back in that truck, plowed a bunch of snow, too.
Freshened up the heads a few years ago and that's all that's been done since it was rebuilt in the 70s.
Came from the factory with an aluminum intake.
The block has the extra webbing to strengthen the mains.
I'm pretty fond of mine.

428PI went into the majority of 1967 Shelby GT500s. Great power, especially in a lighter car.

I had a 68 Shelby GT500 with the 428PI and it ran hard. I believe Shelby changed the name to GT500KR when he started putting the 428CJ's in them.

66 P Code 428s had solid lifters, 67 and up had hydraulic.

Q code is the regular 428.

428 P and Q had the smaller valves.

I=2.022"-2.037" E= 1.551"-1.556"

Intakes and cams changed over the years, the P was in the Shelbys until the CJ.

Cast iron (all after 12/1968 except Shelby)
Aluminum ("P" thru 12/1968 & all Shelby GT 500)

Autolite 4100 (4V-1966-67)
Autolite 4300 (4V-1968-70)

Holley 4160 (2x4V- 1967 Shelby GT 500)

Holley 4150 (4V -1968 Shelby GT 500)

Put a set of Edelbrock heads on it and it will fly and is pretty light for a big block.
