Police Engine?

3500? wow. Mine shifts at 4100ish. 100% stock tranny as far as I know.

Stall, not shift. ;-)

I didn't notice anyone confusing stall speed and shift points ....


johnunit, get yourself a AOD-HIREV kit, pronto!

[Lincolnmania]

no no no the hi-rev kit does not play well with the police aod valve body

VERY good to know. I was planning on doing the hi-rev kit after the 4-barrel swap. Simulators indicate I'd be shifting before peak HP with the 4-barrel top end.


now I just have to figure out if I actually have the police valvebody. Canadian 351w cars only got some of the heavy duty police stuff. Is there a part number or stamping I could check by pulling the pan and filter?

There was a police interceptor spec 428 FE. Pretty sure Dodge had some police spec 440s too

We had a early 70's 460 powered sheriff's surplus and a 77 gran fury 440 police surplus. The Plymouth radar'd at 156 mph when they tested it after put in service.
I was old enough to drive the 440 and that one and it was real strong. I was younger when we had the 460, but I don't think it was as strong as the 440 car.

Miss that Mopar.

For the record there was a police interceptor 460 ci in 1973 only that made 274 HP @ 4600 RPM and 392 Ft/Lbs at a ridiculous 2800 RPM. The regular 460 found in the Marquis and other models were rated at 202 HP that year.
The 351C 2V in my Cougar that year was only 164 HP and was constantly begging me for headers, a four barrel conversion, and it even wanted the Austrailian head swap.Too bad I was poor.

Interesting, I had not heard that. How does it act up?

It does seem that no one actually runs police valvebodies unless they mean to leave their P72 100% stock.

i meant the hp kit which includes the hi rev kit, if anyone wants the hp kit in a police aod they need to pick up a stock non police valve body to do the shift kit to

I do recall, the ford we had was a 73 brown sedan. Kinda looked like the one Burt drove in Gator.

Only 180HP? Really?

According to a book I have, the power output of the 351W used in Ford Police cars depends on the year model.

According to the figures in the book, these are the two horsepower ratings of the 351 in the Ford Panther by year (I assume that the higher power rating is w/dual exhaust, while the lower rating is with single):

1979:
142
151

1980:
130
140

1981:
(no "low output" 351 offered)
145

1982:
(no "low output" 351 offered)
165 (police only)

1983:
(no low output)
165 (police only)

1984-1991:
(no low output)
180 (police only)

My understanding from doing some research is that in the 1984-1991 versions, a new cam profile was used, which is responsible for the jump in hp over previous years.

While these hp ratings seem low by today's standards, bear in mind that in the late 70's there were many cars on the road that were lucky to be able to do 60mph in a headwind. For example, there were lots of 4cylinder Vegas, Pintos, K-cars, as well as lots of the old-school air-cooled VW's (I had a '64 Beetle that was rated at a whopping 40hp), and small Japanese cars that weren't much more powerful than a Vega or Pinto.

[1987cp]

'03 2.2L Chevrolet: 140hp
'08 2.5L Scoobaru: 170hp
'11 2.0L Kia: 156hp
'90 2.3L GM "Quad4" HO: 190hp

Reported numbers from a recent NA 347 build: 694hp

Have I complained lately that Ford deliberately went out of their way to make stock Windsor engines suck?

[1990LTD]

Emissions regulations do all kinds of wonderful things to power output.

Put a quad 4 in a Panther and see how well it pulls

[johnunit]

it's mainly what happens when you have to make your "high performance" engine work with a 1200rpm torque converter and give it a carb designed from the ground up for "crisp throttle response," and use heads with intake ports that haven't changed significantly since the 60s, and exhaust ports that have actually gotten more restrictive.

It sorta boggles the mind that they couldn't find a way to make those air injection holes without them covering almost literally half the exhaust port.

I wonder if there were many powertrain engineer assinations within the big 3 back in the 70s and 80s?
