I had a "rockcrusher" M22 in the truck before my current. It's a tough transmission but I'd never run it on the streets because the ratios just suck! :rolleyes: The gears are so close together that you can literally shift from first to third (or second to fourth) and lose little acceleration. First gear was something like 2.20, I think.
The Muncie M21/M22 are high HP, low rear geared muscle-car transmissions. For a 235 I believe a Saginaw would be ideal. MUCH cheaper than the Muncies and better ratios.
