OK, so you changed out your motor and as well. I am keeping my 351W in there. Hopefully I wont need to modify my drive shaft. Thanks

Since converting to an AOD last summer, I have added a mild cam (Comp Cams XE256H), and a performer manifold with an Edelbrock 600 CFM carb. Since my objective was a smooth idling engine that made decent power and good torque without impacting fuel economy, I'm still very happy with my 3.00 rearend ratio. If cost was no object, I would probably opt for a 3.25 to get off the line a little quicker. If I was a racer, I'd go much lower. Just my opinion. Everyone's car set-up and performance goals are different. My gutless, V-6 powered '05 Dakota has a 3.55 and it is geared way too high for it's AOD tranny.

Rock, my issues really aren't with getting off the line etc.

My questions are about installing the AOD in place of the FMX, and if there are any surprises to look out for.

I ordered the shifter rod linkage kit and TV cable from Lokar, I have the complete AOD with torque converter and slip yoke, my only concern is wether the drive shaft needs to be modified or not.

My engine is the 351W, performer intake, 625 CFM Carter AFB on top, mustang 351W swap headers - cam is original. Car has plenty of get up and go.

Thanks.

If you can find the right length driveshaft, you will save a bundle. If you can't it is much cheaper to shorten one that's too long than to re-tube one that's too short.
