Exploding Torqueflites

Chris:
I have a slightly heated up 360, probably 360 HP, in a 66 Dart, 3:23 gears, and for the past 15 years I've run a 727 in it. Prior to that I ran a 904, and this time I think I want to go back to the 904 again. This is a 99% street driven car, with maybe 1 or 2 trips per year to the strip. Is there any advantage in going to a manual or reverse manual valve body for this application, and if so, which one? Also, does the manual valve body negate the need for the kickdown linkage, which is always a PITA on these small A Bodies. If I understand correctly, some still need the linkage and some don't.
Thanks.

Sid
