I have been a long time member of Moparts but seldom ever post anymore. Too many people spending too much time on YB and the mentality of the trash or be trashed thread has spilled over onto Moparts IMO. The same subjects are beaten to death ie: pinion angle, 8 3/4 vs. Dana, SB vs. BB, etc. etc. and too many people that seem to know everything about every thread posted.

But back to your original question. I have messed with about every SB combo known except for the R5/P7 motors (i do own a set of P7's though, lol). In my opinion a A833 will not live for long behind 600-700HP. We had a Doug Nash 5 speed behind a 422" W2 motor in gearjammerdart's 3270# 69 Dart that did not live. We now have a 417" W8 nitrous motor and a 5 speed Liberty Equalizer (just like the Pro Stock Cars run) and we broke the input shaft in it last fall.
