Have anyone on here heard of putting 2 speed powerglide internals into a turbo 350 transmission case. I have heard of guys doing this in racing classes at circle tracks doing this for the optimum gear ratios when the powerglide is prohibited. But I haven't been able to find any tachnical information explaining how this is done. The local tranny shops here won't speak to you unless you are getting the work done there, and I don't pay anyone to do work I do my self, whether its building an engine, tranny, our chassis fab.Any help would be appreciated.

I've heard of it since Powerglides and TH350's are getting super hard to find here, but there are only a couple of shops i know that would touch it. One is up in Lachine, Quebec. The other is over in the Burlington VT area.
