Somehow, I missed Lgriffin's post about the A-833. Looked at it and it's damn-near exactly what I need. Can anyone vouch for it and does anyone know anything about it? Would a chrysler tranny work in a buick/chevy engine/car? Seems like I could drop highway rpm to 2000-2200 going 70mph. Would this be reasonable?

69 Buick Special Deluxe. Intercooled Turbo Chevy 250 @ 15psi on a stock long block. It's kinda fast.
