Ok, I think we can put this one to rest. One of the things I really like about this site is the diversity of opinions, experience and personalities. I've heard from several if you that i should keep the 8 3/4 cause it can hold up to almost anything and others think I should toss it in favor of a Dana. I'm doing both.I'm having a new gear set installed (3:55) and down the road I'm having a Dana set up and going back to 4:10 with a Gear Vendor O/D.I'm an old drag racer and I built this car to beat on. Differentials are something you should be able to build once with good parts and then forget about. That's why I went with a chromoly driveshaft, 10 spline chromoly diff yolk, new clutches and ring & pinion. Just didn't work out. So, I'll pamper the car until I get the heavier rear axle in and then go out and flog it. Thanks for everyone's response and input. I really enjoy being part of this group and I hope to get together with you at a mopar event somewhere. Speaking of, planning to attend cruising the coast again in Mississippi. Takers?
Sent from my iPhoneTravis,--You mention the race-grade gears - my understanding is that the race gears have a different metallurgy and finishing processes and are designed to survive the rigors of racing, but not stop and go street driving. I had a 4.89 set years ago that didn't last long and it was suggested to me that being the "race gears" that was what happened. My cars have all been fairly heavy (even my A-Body is 3600 lbs with me in it) and can carry the front wheels, but have all been TorqueFlites. No matter what you put in it, I'd make sure it's not the race gears.Gorgeous car, by the way... checked out Gary's link and the car is outstanding.Mike Creglow, what are you running in your '65, street or race gears? That car is a beast... do you street drive it or is it a dedicated race car?SC

Forget about fuel economy, I'm getting 250 miles per Richmond ring gear. I've seen a lot of Mopar race cars with 8 3/4s under them, even some with stock axles but this one broke the first time I jumped on it with the new tires. For those of you with sticky tires, am I wasting my time with a 742 or should I go ahead and start scavenging for a DANA? 4 speed, 4:10, drag radials (occasionally), street car (usually). Glad I stuck a magnet in the diff reservoir which kept the broken teeth out of the chunk. Would appreciate some feedback. Thanks
