I will be using an AOD transmission in my 77 that will be behind a 302. I was wondering which fly wheel to run and if anyone else had done this upgrade? The transmission is out of a 93 if that makes any difference

 

Automatic transmissions don't use flywheels.. It's a flex plate you are seeking.

What year is your engine? Cuz yes, it makes a difference which flex plate... a late 302 requires a 50 oz. imbalance. Early Windsors, 81 or 82 and earlier (I forget which), use a 28 oz. imbalance.

No feedback in tooth count... I'm a three-pedal guy.

 

engine is a 77

 

I really need to know which is the way I have to go and will it require me to run a different starter or a factory starter

 

77 should be 28oz balance. 351/5.8 always stayed with 28oz and didn't change like 302. Just get a flexplate from a pickup with AOD and 5.8. All AOD's had same ring gear count. 50oz weight will look about 2 times as big as the 28. Lots of reading on AOD swaps everywhere. Should be able to use same starter.
