Thank you 32 cyclone,

Would an early 1938 Buick transmission have the same diameter torque tube as the Chevy? A friend of mine used the Buick behind a built sbc with good results in 1957. The Chevy transmission is geared as though it were meant to be a four speed, but somebody left out third gear.

Jack,

I believe the radiator is too close to the grille on 33 to allow the placement of a pusher fan.

Thank you for the responses.
