I have 1956 Chevrolet Bel Air, the engine is a 380 horsepower, the transmission is a beef up 350 automatic with a 2500 RPM stall torque converter. The rear differential has 4.11 gears, I ‘m thinking of replacing the 350 trans with a 2004R unit. Do you for see or know of the problems I will encounter do this transmission swap, like will I need to change to a new transmission mount?
