Exploding Torqueflites

I had a fErd a couple years ago, that was all Mopar running gear, including the front suspension (a '56 HT). The BB 383, had a 727 Auto, with "B&M" components, I was told.

The reverse valve body worked well. If I kept the trans. in 1st gear, accelerated a little, the trans. would "glide" when I took my foot off the accelerator (the only way I can describe it) as if I'd put the transmission in neutral, but, if I used the throttle a little, to bring it up to speed (what would be the equivalent to the road speed) the trans would engage normally. Was this the reverse valve body, or something else in the transmission.

The reason I'm asking, I'm building a 392 Hemi Dart, and have several options for transmissions. I really liked the feature in that combination described above, and if I could duplicate it with this car, I think the small block 727 would be my choice. I'm not a transmission guy at all, never had an automatic apart, but I guess there's a first time for everything.

Please enlighten me..! :argue:

I had a 1970 GTX with a 440 b&m trans and 9" 4200 stall converter do that, I could criuse in first gear to about 30mph, then let off gas pedal and rev it some while still rolling, kinda fun.:read2:, boy the old street racing days, the 80's were fun:cheers:
