Possible to build a solid 8.25" ?

I have seen articles that state you can build the 8.25 to last behind a 600HP small block auto combo in an A-body. Don't know how true that is but lots of people with stout small blocks that race regularly use them sucessfully.

I have one in my 68 Barracuda (3.55 sure-grip) which had been under a 69 Dart with a 360/380 crate motor for several years with no problems.

One point though. You can't change gears to 3.21 or 3.55 with the differential in the rear end. To accept the 2.46 gears it was machined differently and you can mount the higher ratio gears on it. This would be a perfect opportunity to get a limited slip differential for it.
