833 OD behind a 340?

I've got an 833 OD that's going in behind the 340 in my Challenger. If it works out right, it should be making about 400 hp. I've asked this same question myself over at cuda-challenger when I was spec'ing things out. There's a few guys over there that have run 833 OD's behind 440's for years without issue. I suspect it will wear out faster than a regular 833, but how much faster is anyone's guess, it'll depend on how you drive it as well.

I'm guessing if you want a OD transmission you're building a street car, not a racer. In that setting, it shouldn't be a problem. As pointed out, one of the wear issues is a high gear problem, which isn't where most of the hard use typically is. I've heard of the aluminum casing wearing as well where the shafts are mounted, but this is again a long duration problem, not something that shows up after a trip or two to the strip. The main shaft itself is a little smaller, the OD isn't as strong as a regular 833. But for a 330 hp street car, that shouldn't be a problem at all.

The way I see it, I bought 2 833 OD's for about $350. Both are in really good shape, and cores can usually be had for between 100 and 200 bucks. Even at that price they're well under the cost of a regular 833. If they last long enough for me to save up and put a 5 or 6 speed in my car, they've more than done their job.

Here's a link to a thread over on cuda-challenger. I think it was actually a for sale thread, but if you read through it a couple of guys mention using OD's behind big blocks. One raced a duster with a 440 and an 833 OD for 8 seasons without issue...:shock:
