My 55 presently has a 351 with a wrong cam so I bumped the gears from 2.79 to 3.00 and the motor is spinning more then I thought at 70 on the highway,those gears perked it up some around town but not as much as a I would like so I am thinking about going with 3.25 gears and a AOD with a Lentech valve body. I wanted to got with a FMX so I could use the original type starter but the AOD is starting to sound good so I can have a gear so it will run good around town and go comfortably down the highway.

Butchering up everything I can get my hands on in Dayton Ohio
