428 PI Question

http://66ford.fordregistries.com/
At the above link is a brochure for the '66
cop package, it states the 428 PI (code P, 360 HP) is a solid lifter engine. I honestly think this is a mistake as could swear the
PI is hydraulic. Whos's right?

428 PI Question

I seem to think the Police engines had a hydraulic cam. I have never seen a 66 though.
I have also read that Seven Litre's came with a solid. I know from seeing them that the one's I saw were hydraulic. Many people make the story better each time they tell it, and never let the Truth stand in the way of completing a good tale.

428 PI Question

My 66 345 HP 428 was a factory hyd cam but, I switched over to a Erson solid grind for a little more "giddyup" and "retro" solid lifter sound .spin:

428 PI Question

I'm probably wrong but I thought all PI engines had solid lifter cams... or was it just solid lifters? *scratches head* See, don't ever take my word as proof 'cause I usually confuse myself. lol

Now didn't the aluminum intake always come with the PI option?

428 PI Question

Early '66 428 PI's came with solid cams, but the literature rarely says so. My old man and I pulled a legit solid lifter 428 PI out of a '66 LTD years ago.

Has anyone actually seen an aluminum PI intake on a Police Interceptor engine? We've had two, the '66 LTD and a '70 Merc Monterey ex-CHP cruiser, and neither had the aluminum intake. The LTD had a regular 4BBL piece, and the Merc had a CJ intake.

this is an ancient thread and I just joined but here goes anyway.very early 66 428 Pi engines came with solid tappets,they used an identical cam to the c3ae-AA 427 cam except with no oil grooves.the intake was an aluminum with casting numbers C6AE-9425-E, I beleive later replaced by C6AE-9424-H.Another oddity is due to the adjustable rockers and .500 lift cam they installed painted pentroof 427 style rocker covers.Later in the year they went to hyd lifters and a cam with less lift and duration along with an HP drop from 360 to 345.This is based on personal experience as well as things I have now and have seen in the past,good luck,Tim

Hey Mr.M,
John Smith's book: "Super '60s Fords" says on P.58:

"The largest displacement engine in the 1966 Ford lineup was the new 428cid 4-barrel Police Interceptor 7-Liter V-8, with 360 horsepower at 5400rpm, 459 lbs-ft of torque at 3200rpm, 10.5:1 compression ratio, hydraulic valve lifters and a single 780cfm Holley 4-barrel carburetor on an aluminum intake manifold. The entire engine was dark "Ford blue" in color. Replacing the old 390 P.I. engine, and supposedly available only to law enforcement agencies, Fords originally equipped with this engine carry the "P" engine code on the data tag."

BUT, you can take that with a grain of salt, for he also said on P.33:

"As in the previous three years, the Police Interceptor continued to be available for "law enforcement" use. The PI 390 featured 330 horsepower at 5000rpm, 437 lbs-ft of torque at 3700rpm, with a 10.1:1 compression ratio, high-lift mechanical camshaft, and a single 600cfm Holly 4-barrel carburetor on an aluminum intake manifold. The engine block and cylinder heads were black in color, with gold valve covers and air cleaner. Fords originally equipped with this engine carry the "P" engine code on the data tag."

The above paragraph has two "glaring" mis-statements:

1. I have a 1964 Ford Galaxie 500, Four-door, Hard-top, Fast-back, Police Interceptor and it came with a CAST IRON intake manifold.

1964 FORD GALAXIE 500 PI

2. Although it has a Holley 4150 650cfm carburetor (put on as an after-market item), it originally came with an Autolite 4100 1.12 C3AF 9510 (with various suffix letters such as BY, BU, and BZ, depending on the kind of transmission). The Holley will soon be replaced with an Autolite 4100 1.12 C4AF 9510 DG, which has just been restored.

Autolite 4100 1.12 C4AF-9510 DG Carburetor

What we NEED around here is someone with a 1966 PI that hasn't been molested. That would solve the mystery!

Hope you are well.

JC

Misfit41 is correct on this JC

The 428 was released in 1966 for increased power/performance for the FORD, MERC and BIRD. The passenger car engine was hydraulic and rated @ 345HP. A Police version (not regular option) was released with a solid cam and other goodies and was rated @ 360HP. The 390PI was dropped in 1965. The 67/70 428PI was hydraulic.

To my knowing this is correct . Most pi motors were solid and a family car was hydrolic . The cj and scj was released in June 1st 1967 and all of those were hydrolic .

Re: 428 PI Question

I have an original unmolested 428 PI engine in my 1966 AC Shelby Cobra, CSX 3288. It has the aluminum PI intake and an engine tag that reads
"428 66 1"
"6 B 404 S"

I do not know whether it has solid or hydraulic lifters (doesn't sound like solid lifters to me). My question relates to the correct distriubutor for this engine with those dates. Bill Carroll's Fooorrd V8 Performance Guide suggests it should have a 12127-L dual point, but my Ford master parts catalog lists 12127-AH single point distributor. Any ideas? Thanks.

Re: 428 PI Question

The Shelby sales brochure for the 428 equipped cars states "hydraulic camshaft".
