Your going to want some stall with your mud bogging intentions. A quality vert will stall where you need and provide very little slippage at highway speeds. My vote a 9.5" 3800 stall Dynamic, or something similer from ati or so. I would not go Less then that with your overall intended combo. If you do, you would be leaving performance on the table.
I agree as I run a Dynamic 9.5 in my 63 and in my sons Dart. And we both love them as its their street/strip converters that drive great and work nice at the track. Mine is rated at a 4200 flash but I can cruise at 2500 to 3200 rpm all day long with no slippage or heat buildup. I love it as its been in my 63 since 2006 and still going strong and my 63 is a 99% street car. Ron
