Yeah, The Chevy powerglide and turbo glide are 2 spds, low and high but there both usally pretty low, they are on my '51 and the old glides can't take the beating, you could probably order a drag racing powerglide from summit and bolt that up and that tranny would take the beating and if you did blow that tranny, parts are available from summit to rebuild that although they are geared more for drag racing but, you should be able to get away with using it. Another option is the TH350 transmission, would take it also.
