Allan, the father of Adam, are partners in this company is what I've been told
I've bought a bunch of converters over the years, some bad, Art Carr, GER, early TCI and probally some others I can't remember now. I also bought a 8 inch race converter from Marv Ripesat A1 and he took care of the maintenance on my stockers trannys for that year, that converter was excellent I've also bought good converters from Turbo Action, a early 9 inch 069J BM, Rossi and several other all out race only converters company in SO CA.
My main message is to not skimp or buy the cheaper ones, you get what you pay for
