Exiting a corner in 3rd (5900 rpm shift point with my 4.6), the plots practically fall on top of each other - no surprise there, really.

But even using 2nd with the Magnum doesn't help - you gain a little for the few mph that you're using 2nd, but you give it back with the extra shift and the slightly taller 3rd gear. Way out past 2000 feet, having an 0.80 5th in the Magnum vs 0.68 in the 3650 begins to catch up.View attachment 67743
A big thank-you for the real-world feedback. It means a lot.I've run these 3650 vs T56 several times, and I'm with you. The only reason a T56 is in my future is the torque rating. If I do toast the 3650, I have to go back better, stronger, faster (or whatever the quote from Six MM $ Man was).
"Keep on trucking" Norm! It's good to stay focused on a project or two. I just had my knee replacement surgery Fri. so I'm out of the driver seat for 4-6 weeks !!! I'm already getting impatient ! Lots of work to finish on my Boss.Well, I'm slowly getting back into this project. I'd gotten only partway through the Torsen/3.73 swap before having to button everything up for a while.
Anyhoo . . . I'm starting to make a little progress. I never was entirely sure the pinion depth was going to be where it's supposed to be but based on notes I'd taken before I think it's going to be close enough. Naturally after measuring pinion head and shimming so I could run the numbers based on the replacement Ratech tool, I stumbled across the one I'd bought before. Grrrr.
The good news is that if my notes were any good, I may be a few thousandths closer with the 3.73 pinion as shimmed to essentially the same thickness as the 3.55 was originally than the 355 was. We'll see . . .
Here's what I put together today for taking the play out of the pinion bearings while doing the Ratech measuring thing. I'd hoped to find a short length of tube, but that didn't happen.

A couple of people are aware of why my current progress is slow, but the short story is I'm dealing with a medical issue that from time to time limits what I can - or should - do. Never mind that if I went at it anyway it would make my wife kind of nervous. Maybe I'll have some pinion depth measurements made (and double checked with the tool I thought I'd lost).
