Ford flywheels and flexplates are apparently a very vexing topic for many people working on engine or transmission swaps like I was. As I researched the details for myself, it became very apparent that it's a confusing topic for many folks and that there are various sites out there that attempt to explain it. Since I had to read a bunch of sites to decipher things, I decided to start my own page to pull all this together in one place. NOTE: This page is specific to the (now) older Windsor Ford V8 engines, and my specific work was on 302/5.0L engines. That same basics should work on the 351/5.8L engines, and the 289 engines as well, but, I have not confirmed that. The information on this page does NOT apply to the later 4.6L, 5.4L, and other "modular" engines! Extrapolating this information to anything else should be done only after careful comparison of actual parts or other authoritative sources of information. Using the wrong flywheel or flexplate on your engine can - quite literally - destroy it due to excessive vibration due to the wrong balance weight, so use common sense and lots of care in selecting the flywheel to use. I am not responsible if you break your engine, transmission, or anything else as a result of you using the information on this page. This information is for educational purposes only, and has no warranty or guarantee of being correct for your particular needs.
I hope it's ok to add this here. I was surprised I didn't see it on that site, but it may not be a popular swap.
For anyone that wants to put an AOD behind a 351w you can not use the C6 flexplate - you'll eat your transmission in a few miles. There is approximately a 1/4" difference in where the torque converter sits. The C6 flexplate will push the TC too far into the trans.
What you need is a flexplate from an 89 Crown Vic with the 351w/AOD combo. Actually, any early 302 or 351w mated to a C5 of FMX trans will also work.
