thank you for the input so far.

I am looking at 850-1000 hp. (not 2000hp)
STreet STrip Car

Fairly heavy mostly all steel B body
Procharger car

I am not a tightwade but I would like to pay the price and get the correct tranny for my application once
regardless if it is a gm tranny or the 727

So the technical reasons would be great


1970 Barracuda Convertible
1968 Satellite Street Strip car
1654.5 Mustang
1955 Land Rover
