Trans swap

Thinking of changing trans to a later model 5 speed. What am I in for? I currently have a T-18 with a 351M motor.

The biggest issue is that you have a 335 series engine, no 5 speeds were ever put behind them stock. That said they have the same bell housing as a big block and they did put the ZF5 behind the 460. There's a thread in here somewhere about putting a ZF5 behind a 335, IIRC it's by Gary Lewis and titled Dad's Transmission.
