You would need a V8 bell housing from a 1955 2nd. series or newer truck, and the corresponding crossmember it bolts to, plus the standard shift flywheel and clutch for a Chevy V8 engine. Adapting the linkage from the original clutch pedal to the V8 bellhousing will probably be a challenge. It's possible you will encounter very difficult shift linkage issues as well. If you manage to get everything connected and working, you will have a transmission and rear end that is seriously under-capacity for the horsepower and torque of a 305 engine. Back in the early 1960's I worked for a man who adapted a 55 Chevy 265 engine to a 1940 Chevy coupe, using the original transmission and rear end. The first time he revved the engine up and popped the clutch, the transmission cluster gear went out of the bottom of the case. He was sitting at the starting line of Union Hill drag strip in Springfield Tennessee at the time! Major embarrassment!
