Rear-end weight difference

Of all my years of research, you're the first person I've ever heard say that. I know that if you can find one of the rare-as-hen's-teeth 7 1/4" sure-grips, it can help with durability, but even slanters regularly blow out their 7 1/4"s when they start to add power (according the folks over at .org). My long-rod 225 is already making a lot more power than stock. I figure the lower gears, the planned T-5, and further upgrades will eventually toast the 7 1/4" in my Swinger, and I'd rather build in some insurance and add a lower ratio.

My only personal failure experience is with my 273 2bbl '67 Dart, totally stock. The current 7 1/4" rear howls like a banshee. Regardless, I'll likely swap the Swinger's rear into the '67 when I install the 8 3/4" in the Swinger, just because it's free and, thus far, quiet.

I will ask you again.
Did you break it?
You say with your upgrades you will eventually toast it,but you still havent broke one yet.
Like another said they regullary put these in 318 cars(with 230hp,good luck achieving that with your slant)and they hold up.

7 1/4 howls like a banshee......well after some 30 yrs of service you would howell to,and that still isnt failure.Any rear will howell after time,and need to be rebuilt.

You are right though,I have no clue on what I am talking about. :sad:
