Quote: The question was: will an 8-3/4 live behind a street small-block in an A-Body.
Mine lived behind my street/strip 340, it died on the third pass behind my 408. It was a Richmond 4.30 on a clutch type carrier and had about 60 passes and 1500 street miles. My Dart weighed 3240# at the time, the 408 runs on pump 93 and gets driven often. The converter flashes 5000. I ordered a new S-60 from Strange, it was less than $1900 shipped to my work.
I broke two stock 9" rears in a Ford truck I had. The first busted the case where the small rear bearing is housed for the pinion while pulling a truck with a pontoon boat up a boat ramp. The second busted with a stock trailer loaded with cattle. The truck had a four speed and was in granny low both times, and no I didn't rev it and dump the clutch. That was the last half ton truck used on the farm.
I know the 9" rears can be made strong but if it's stock it's no better than a 8 3/4. Give me a Dana.
Someone posted the weights of an "all iron" 9" and a S-60, IIRC it was around 40 pounds. If I'm wrong some one please correct me.
