I dunno, uncle Tony just did a video and in the video he explains the benefits of using a 7.25 rear end. Makes perfect sense and I do think the 7.25 is underrated and there is a good reason Chrysler used it in 10 gazillion cars.
I priced gears for a 7.25 and only one I found was a 3.55 gear set from Yukon axles for $349.
I really don't see the economics in a 7.25 when a ford 8.8 is readily available and the gears are cheaper than that and in a much wider selection and limited slip units are here, there and everywhere...... chances are, there are a few parked in your neighborhood right now.
I an trying to give the 7.25 a chance because I have a bunch of them but I'm not seeing where they are so cheap and easy to work with. I would need far better gear selection at a good price and available sure grips that won't cost a grand.
