Thanks Whitedog! Found the website and reached out. Awesome that he has this stuff. He mentioned he has one in his '51, sounds like it's up and running as well.
I especially like the transmission conversion plate he has so we can run a more 'standard' transmission. I think the stock ones mated to the 4200 were a little iffy, seen quite a few Trailblazers, etc for sale with blown transmissions.
