Dana 60 vs 8 3/4 -Steve Magnante Hemi Dart

That's interesting. A 50lb weight reduction on an 11 sec car should reduce ET by a couple 10ths? But of course some of this weight reduction is drivetrain rotating weight. Which in testing with flywheels? Lighter doesn't always equate to faster.

My A-body has an 8 3/4" rear. My B and E-bodies Dana. And I haven't a complaint with either. I would be interested seeing same test with 600+ HP. And even more relevance? Manual transmission vs automatic? We have been told that Manual transmissions are rougher on rear-ends? (Manufacturers mention primarily due to driver habits.) But I personally have no evidence to substantiate that claim against clutch cars?
