I just located a 235 from a 61 Biscayne with 3 speed manual. I'm going to put a deposit on motor tomorrow and am wondering if I should get the tranny. I want to change out the torque tube rear & tranny in the 51. The old guy at the bone yard said the original 51 3 speed is pretty weak. I want some form of manual, on the floor would be nice. I understand that 55 - 57 rear end will fit. Any suggestions?

Thanks,
sherman
