I've eaten more than a few 23-spline A833s with a healthy small block, road-course type use. Shucked teeth right off the countershaft and speed gears. Even built boxes with new (NOS '60s) gears, still ate 'em. This was in a light A-body, too. I was really bummed to have to walk away from the 3.09:1 first, but there was no other option.

18-spline or modern tranny swap. No other viable options. That's my 2¢.
