Powerglide 2speed tranny have been used for racing for a long time. Not really knowing what the Q,as it was not layed out well. I'll rambull some. Back in the late 1970s Winters Performance put out a kit to build your own for dirt oval racing. I got the kit and built my own,but I was racing on blacktop,not dirt,an my Latemodel Mod was making well over 400hp. So it took me 9 race weekends too redesign one to work on blacktop with big HP n 10in. wide rubber,brake it an fix next week point for 8 times. Something TCI never could do. The clutch pedal,I hooked to a 1/2in. ball valve,to control pump PSI that I made to 160. I redesign valve body and size of servo feed lines. The Winter's drive to replace T-C was the only thing not needing big mods. Even the alum PG case had to be reinforced. The drive was this design. https://www.ebay.com/itm/234178596052?
Are you talking about a mount at the back of the block? Unless you go to a full mid-plate maybe these would do what you're asking. https://www.summitracing.com/parts/...hX7iwz3wWlNry-zxqE0PIPz0LGmdu7FhoC3z4QAvD_BwE But, that might not be even close to what you're asking. Lynn
Was that in the Retro-Encabulator or the Turboencabulator... or was that the Entabulator? It's been a while since I've surmounted my two spurving bearings... but that might be a personal problem.
