https://fordauthority.com/wp-content/uploads/2019/10/Ford-3.7L-Duratec-37-009.jpg

 

 

The Duratec 37 is a naturally aspirated V6 engine from Ford Motor used to power midsize and full-size sedans, sports cars, pickup trucks and utility vehicles, or more commonly known as SUVs. Featuring a dual overhead cam (DOHC) design, in a V configuration, the Ford 3.7L Duratec architecture has been part of the Ford Cyclone engine family since 2008.

Sharing many of its internal components with the Ford 3.5L Duratec 35 Engine, the Duratec 37 was initially intended to power heavier or premium vehicles within the Ford, Lincoln and Mazda lineup. As a matter of fact, the first iteration of this engine was in the 2008 Mazda CX-9, where the engine was built in Hiroshima, Japan under the MZI 3.7 name. It was then used for the 2009 Lincoln MKS.

Just like the rest of the Cyclone engine family, the Ford 3.7L Duratec 37 engine utilizes a twin independent variable cam timing (Ti-VCT) system for optimal performance deliver and fuel economy. The engine powers the following vehicles:

@Buboyeah , iron block , aluminium heads , the last Iron LT1 made before the all Aluminium engines  ,the Vette motor was more reliable  that the non LT1 Caprice classic  350/ 5.7 liter Police  cars  that were sold by GM  before 95 ,same engines as in  the Camaro Police Pursuit cars  used on the Highways  -

I watched the Fleetwood Broughams roll off the truck as they came on that year. It was not uncommon for a million mile limousine to roll in to the shop using that exact powertrain.

How much weight did the aluminum drive shaft take off ?

The vette mill was iron block ?

Don't recall exactly but it did weigh less. It was the extreme improvement to the balance over the other that made high speeds so smooth!

F-Body LT1s had differences, I used some of the smog-stuff off of the F's order list to improve the breathing in my B Block. Old school iron blocks can take more abuse. Couldn't put headers on mine in NC for smog monitored vehicle engines. The 9C1 manifolds were larger though. Such a clean burning motor that emissions were close to nil... even after I modified the cats. Would have loved to have an LT-4 powered rod.

Update

 

One of the nearby Ford Dealers is dabbling in used Interceptors

So I went for my first evaluations and test drives

 

Asking Price $15,500

The 23Kmi Clean CarFax Taurus I went to view hadn't been made ready for sale yet, "just in"

- Passenger's side t-bone, pushed in at least 6-8 inches

- Every Body panel crooked inc driver's side doors

- Back seat cushions tossed in the back of the car

- No spare, water in the Trunk well

- 4in round Hole in the Driver's side dash between dash and door

- With the seat out, the A-frame suspension reinforcement of box Steel was clearly visible.  I believe the rear seat cushion is closely shaved to make room for the box steel underneath.

- Roof antennae mount in place, 1in hole in roof

- 3 1/4 in holes above front doors, where lights bar were mounted.

- Giant stock island between front seats to prevent man spreading

- Terrible rear visibility

- Side mirrors worked flawlessly

 

With the salesman, I test drove it to a local body shop I know, and asked the estimator to take a look. He burst out in laughter, and kept looking OVER at the straight faced salesman as he quickly went through the car.

"$5K minimum to get started"

 

They had two other Taurus Interceptors on the lot

I passed on both, which had been made ready for sale.

 

I moved on to the one Explorer Police Utility they had on the lot

- Body panels lined up properly, probably no accidents

- Inside clean and in tact, missing island with unfinished hole in between seats

- Hands free stopped and accelerated straight

- low speed slalom, vehicle was stable and no rolling. I'm pretty sure there are vehicles I can flip at 5-10 mph, others just wallow side to side

- Acceleration from  stop was quick

- Acceleration from road speed, 2-3 gear downshift and lots of exhaust system tuned growling, not sure it actually accelerated. But it sounded really fast.

- Engine had a miss, or broken mount or both

- Cabin Heat system farted on us when I changed the temp, probably coolant leak in core ($1500-2500).

- Terrible rear visibility

- Side mirrors worked flawlessly

 

Pre used car inflation, the SUV for $3- 5K might have been worth taking to round 2

The Taurus was purchased at Auction, probably for it's full value, $600

- Which if you bought 2 and pieced them together, may have been a good deal, if you could do all of the work.

 

Wild Card Engine Idle hours

- If multiplied by 60 as suggested by a fleet manager, SUV had approx = 500,000 miles on engine

- If multiplied to match engine operation hours/miles the SUV had 130,000 miles on it

 

Used car market is bleak

Looking at used vehicles and ran across used Police Vehicles

 

Pros

Lower cost than similar civilian

Performance tuning and suspension, better brakes

Regular oil changes and brakes

Everyone slams on the brakes when you are passing by

 

Cons

Engine idle hours are very high

Have seen idle hours equated to 10x up to 60x

The Fleet argument being that the cooling sitting still is ineffective

Water accumulation in the engine etc

Police are believed to drive the vehicles hard for various reasons

Rubberized floors are slippery

- good for vomit, blood, urine etc ...

 

In the cars

Charger Hemi full time rear drive, 4 wheel when needed

Taurus 3.7 smoking performance, 3x parts costs due to patents

Full time front drive, 4 wheel when needed

4-6 mpg better than charger

Taurus is half the price of the Hemis, due to demand ?

 

In the SUVs

It's explorer vs Durango vs Tahoe and a few suburbans

 

Any thoughts or comments ?

 

I can only say Don't do it 🍻

One of the of the last, if not The Last source you'd ever want to buy a used car from is Law Enforcement. If you don't get it, ask a Trooper/Sherriff/Local PoPo

The search for a top tier car from the past can be a lot of fun, if you choose right and find a good one. Such as this 2008 Mercedes S600.

 

 

— just be sure to have the equivalent amount of the purchase price in savings for future repairs. I had a certified MB master technician literally pull me by the arm and away from purchasing an S65.

They are used by all Shifts.... A gets off B uses it and passes it to C shift. They don't turn them off... Idle time on these vehicles is something else. Not to mention the driving abuse they take.

nope , that's not the case with all  Police Departments  ,in our  area ,  Cruisers  are restricted to 1...... 8 hour shift , other shifts have different cars  , the cars are serviced and kept in an A1 condition , and most Officers would Buy their cars if they were allowed to do so  -

Vegas is still the optimal location for that right?   Just asking for a friend. 

I believe I would look into mail order brides from across the pond. The ones in Vegas have their oil checked constantly and are serviced regularly. Personally, I would stay away from the upgraded and modified models. Even the newer models might have been ran hard, curbed or might be a total wreck with a rebuilt title. 

@Bubo It looks like you're doing the homework it takes to get the right car. I bought a CNC mill off of a government auction site that was in a vocational school. I would rather have that than one ran for production. It was like new and was factory serviced.

I have looked at getting a motorcycle. They usually fetch a lot less than street value.
