489 vs. 741

Saying the 741 is "weak" is simply spreading mis-information. Straight from Dr Diff:

Pinion Comparison - Quality Body Shop Drivetrain

No ****!!!

Another episode in the mopar lore of misinformation, akin to 340 intakes on 318 heads is horrible... :)

The day the pinion bearing size becomes the weak point in a 741 case is the day the earth stops rotating. It's not the weak point in ANY of the cases!
