Does anyone know 727specialist

I have bought two 904s from keith. Never any problems. I Took two cores down to his shop, and got two really nice 904s. I wouldn't be scared of his traany work.
All he does is Mopar Trannys.
If I remember right he has different levels of rebuilds Stock, mild, Or race, or something like that.
He was working at a Mopar Dealership in Indiana. He is just east the Illinois/Indiana, out side of Chcago.
