I've got a 71 Torino that I'm building and would like some input on which transmission and torque converter I should use. I've got a 351 Cleveland, a 9" rear with 3:50 gears, and a posi differential. I want the car to be pretty quick off the line and still able to cruise at highway speeds. Also prefer to use an automatic. Any suggestions you have would be appreciated. Thanks.

+1. The version for the 3.8 and 4.2L engines will bolt to a Cleveland. You could build or buy an upgraded AOD, but by the time you spend all the money for the upgrade parts, the 4R will bolt-in with fully adjustable shift points, lockups and other characteristics.

BTW - you want a 1998+ (much stronger), but the later ones are electronic speedo, so stick to '98-'00-ish depending on what it came out of. (E-150 and 250, F-150 and 250, Mustang). Unless buying an aftermarket torque converter, the only factory converter that will take over 6000 rpm is the small-diameter "Marauder" version. Do a web search about all that.
