I've got a '99 GT with a Windsor in it and I'm pretty sure that I have a bad rod bearing, before I get too far into pulling the Windsor out I was wondering if the crank from a Romeo would work with the Windsor internals. I just read that the Windsor has thicker connecting rods than the Romeo. Does that mean that it's just the rod itself or the rod to crank mating surface as well? I'm hoping I didn't shoot myself in the foot with buying a Romeo as a donor engine. I also know that the crank in the Windsor is an 8 bolt and the Romeo is a 6 bolt but I didn't think that it should be a problem to get a 6 or 8 bolt flywheel down the road. Any insight would be greatly appreciated.

as far as I've ever heard any 4.6 part will fit any other 4.6, 2V, 3V or 4V

Thanks for the info. Let's hope they're interchangeable. Now time to do some open heart surgery on my poor stang.

The windsor has a slightly heavier rod and more dish in the piston so slightly lower cr . As long as you swap the complete rotating assembly you should be golden and only have to deal with the 6/8 bolt flywheel thingy . I wouldn't mix rod/piston combos .

If you do the swap, use an 11" 6 bolt flywheel and you'll be fine with your current 10.5" clutch setup.

Interesting the changes between 99/00 Windsor cars and 01+ Romeo's. 99/00 had slightly lower compression, more catalytic convertors.... But yet the Romeo with slightly higher c/r and 2 less cats had the same official 260/302 hp&tq rating. Would think that such changes would have had at least a 5 hp +/- effect. Or maybe the changes weren't considered substantial enough to warrant the time and money involved in retesting and certifying the engine?

With the Windsor being a truck engine i imagine the torque number would be more important to Ford as long as the hp #'s for both types fall within the margin of error for the engine series . For the reasons you mention i would expect the Romeo to dyno on average higher than the Windsor . We all know Ford rated the Bullitt with a much better intake manifold at only 265hp and the 5.4 just at 260hp .

More great info. Thanks everyone! Let's hope the swap goes just fine.
