are they interchangeble

[fast97gt]

alrite ive been looking now for a couple months for a reasonible priced, low mile pi motor for my 97gt...my heads getting ready to pop off, i have a crank and rods that came out of a windsor pi with 39.000 miles i picked up 2yrs ago. if i found a npi remeo, even a pi remeo will the crank and rods interchange? thats if i decide to go through the fun of rebuilding one. i did however find a police interceptor with a 150XXX pi in it for $800, would that be buying and replacing the timing set and going with it, or what. ive heard it run and it sound great, no ticks, flutters, knocks, etc. the thing pers like a kitten.

I paid $830 for a 38k PI Romeo motor from a 2004 Crown Vic (non police). I got a complete motor (intake to oil pan). The motor is currently running just great in my 2000 GT.

I would put a new timing set in a 150k motor before re-install.

Try Car-Part.com--Used Auto Parts Market This is a search engine of linked salvage yards.

I would not use a police motor (unless it was very inexpensive). They spend much of their life idling. Mileage is not a good indication of the actual use of the motor. That is why the police also install hour meters in their cars (no joke). The service is done by mileage and/or hours of operation.

but what about the crank, are they interchangeble between the remeo and windsor

OK. I have read through "modular madness" at engine builder as well as George Reid's book "How to Rebuild 4.6/5.4 Liter Ford Engines".

There are notes about changes being done starting for the 1996 model year. As well as notes regarding the material the crank is made of. There are also notes about the counter weight being "knife edged" on some years/applications.

However, I can not find any notes stating that beyond the obvious difference of 6/8 bolt rear crank any Windsor/Romeo differences.

I did find notes about differences in various years of DOHC cranks.

So in 30 minutes worth of research, I haven't been able to find any reason that the 1996+ SOHC Windsor/Romeo cranks are not interchangeable (other than the 6/8 bolt thing).

Disclaimer. I am not an engine builder. In fact, other than replacing bolt on parts that attach to a motor, I have never put one together in my life. I do read a lot (and have spent the night in a Holiday Inn).

i beleiv ive read the same thing, however the only other difference in the two are the main caps, remeo has a jacking bolt, and the windsor has dowels. so anyone else who may know please chime in.

Soooo everyone knows about the differences in the main bearing between Windsor/Romeo. But the question was about the crank itself.

As long as the resulting bearings surfaces are in the same location (size, width, location) the crank wont care which block it is installed in.

Back to the original question. Beyond the differences in the number of crank bolt holes, is there any reason the cranks can't be swapped?

Well I did some home work, and feom what I've found is every vehicle with the vin code X, the rotating assembly takes the same bearings. So that being said the cranks are interchangeble, from the npi in 96 to 04 pi engines. Thanks guys for your help
