1/8th mile ... have you considered a jr dragster?? 
We didn't choose the track, they closed the 1/4 mile track, and opened this one.

Yes, I am aware that cast iron O/D 833's exist, but I don't know how hard or easy they are to find, and at what price?
I am simply wondering if it is possible to covert an aluminum O/D unit by using a standard 833 iron case...just as mine is touted to be by the guy who made the one on my shelf. I don't know what the guy did to mine as I have not looked inside to verify it. All I'm saying is that if such a conversion is possible, it might be a fun, feasible, and inexpensive alternative for people to explore. Especially if they already have some trannys laying around.
If I ever try it out someday and it pukes its parts, I won't be out a lot of cash. At which point I will drop the big bucks on a nice unit. Hopefully by then the McLeod M-800 or Passon trannys will finally hit the market or even some other choices.
It would very easy to verify without opening the case.....just have to put it in high gear and ck the rotation if it's 1-1 you most likely got screwed....if it's over 1-1 or whatever the od ratio is....you win

Hey Rickster! You are brilliant! ...however, I am taking a wild guess here. My approach will be this... If it turns out to be 1 to 1, I'll pretend that I didn't get screwed by being ecstatic that I now have a large expensive door stop! Thanks!

I put an aluminum case OD through a lot of abuse back in the day. They are not the wimps some make you think they are. Like most everything, if you beat the tar out of it, expect it to break at some point. The issue is, if you bought it used, you really don't know how its been treated. If it was the one I had, it might not last much longer.   but if it was like the one I had at the start, you will be good for a while.  Gene
My aluminum one lasted me over ten years that I drove my swb as a dd and it was over 20 years old when I started driving it. I've towed with it & hot rodded it with automatic trans fluid in it. Which it had the automatic fluid in it when I got it.

And both of you had 500hp Bigblocks and slicks correct?
With an actual 500 HP and sticky slicks, and if the truck actually gets traction, the 18 spline 833 will be at its limits. Without traction? The OD will do OK right up to the point you get hooked up.
With a little (or a lot of) effort, I could and did break nearly everything. The point was, the aluminum case OD takes nearly as much abuse as the standard issue iron 833, right up until you pound the case away at the shaft bushings.
The right small block with traction will cause more damage then a big block without traction. Given traction, the teeth on the gears are going to break whenever they feel the need to break. Gene
