I would've thought an actual mopar performance one would be a good one, guess i was wrong. I did send out a bunch of emails lastnight to the custom builders suggested.
What is the diameter is it 10" or 11"? Most folks on here aren't old enough to know that all of the automatic street Hemi cars came with an 10" 2500-2600 stall converter and 3.23 gears.
When I got my 68 B029 SS/AA HEMI cuda it came with a 10" 3500-3600 stall converter it would flash to 3800 on launch. Later after losing the stator sprag, all the talk then was the new B&M 9" 5000 stall converter and it's wow difference so I got one. With the engine at a clean idle of 1800 rpm it would flash to 5200 and pick up the front end and leave HARD big diff.
