I'm going to go look at a 1989 Crown Vic Police Model and possible buy it. I'm more familiar with the 1992 and up PI then the Box Bodies. Did they come with similar equipment like the 1992 and up models ? Its a 5.0L V8 car and is a "White Shirt" car , it has the nicer seats and trim level.

Thanks

That police package might or might not have a 351 or a 302. No rear disc brakes on the 89. Lots of emission stuff on the 89, as Ford was still adding band aids to meet Fed requirements. The 4.6 basically was designed for emission requirements, so the engine compartment is not as "full" as the 86-91 models. That being said, I have an 89 and a 97 and like them both, sort of equally.

Its a 5.0L car. Its white , with blue interior. Its a former KY State Police car. It looks super clean in the pics. I've been looking for a Box Police car for awhile. I want to put 16" or 17' wheels on it. I'm going to redo the engine, just dont know to what extent.

They are basically the same thing mechanically and suspension wise as a equivalent year's towing package. Actually, the police package always was basically the towing package but with a more basic interior. It'll have dual exhaust, the reinforced "heavy duty" frame with firmer shocks, springs, and they have a stiffer front sway bar and actually have a rear bar. There are the typical extra transmission and power steering coolers, pretty sure they didn't have an oil cooler but I could be wrong. They also typically had a 3L55 rear axle from what I recall, unless they had a 351 in which case they had a 2L73, I guess they figured the extra torque of the 351 could push them along good enough with the highway gear. They'll have the larger 11" rear drums with phenolic pistons in the front calipers (pads for those are getting somewhat hard to find locally as we discovered when trying to find some for my buddy's tow package '91 wagon). It'll also more than likely have the higher output "1G" alternator with external regulator. FWIW, in the box era, there actually was such a thing as a heavy duty frame, the '92-'97 Aeros all used what was the box era's heavy duty frame.

If you are putting 16 or 17" wheels on it, definitely consider doing the "big brake upgrade", which is putting '98-'02 front brakes on it. Aside from the stock 5.0 really running out of steam at highway speed with the 3.55s, the biggest annoyance I have with driving box bodies is that the brakes really aren't so great, even with the larger drums and phenolic calipers. There's just no getting around the fact that the front rotors are the same diameter as the rear rotors on a '95-'02. Mighta been okay in the '80s when everything on the road had equally crappy brakes, but a bit unsettling in freeway traffic these days.

How involved is the front brake swap ? Do you have to swap control arms or just the brake and spindle hardware? Can you put an alumina PI driveshaft on them ? It would be easy to make more horse power on a 5.0L

IIRC, it's needing upper control arms with the correct ball joints, the donor spindles, '96-'02 lower ball joint, and all associated brake hardware to go along with it. Check out this link for more information.

An aluminum driveshaft can be fitted, however you may have to use a spacer at the rear axle to make the length correct. Someone did a side by side comparison of Box and Whale PI shafts and in a certain instance they were the same length. Just the use of a different u-joint was required to mate the yoke and shaft combo together.


Making extra HP is easy, dependent on how you decide to do it. The '86+ LoPo engine gives you a fairly decent starting base to do a fair amount of anything, considering it's a roller block. The only thing limiting you is imagination, money, and I think the 500 HP wall where block cracking starts to occur. smile There's plenty of factory/junkyard mods to make cheap power, and of course, the aftermarket is very welcoming to any 302 build. It just depends on whether or not you're trying to stay within stock Ford computer controlled options or going totally aftermarket for fuel and induction. I did the cool kid thing to do like 15 years ago and HO swapped my car this year given the particulars to do that swap kinda landed in my lap, but better options exist now for generally stock upgrades, like the use of the Explorer heads or entire block in general.
