Any smog laws in your area?
You'll need to change the entire drive train: engine, trans, drive shaft, rear axle.
You may need a body lift to make room for the transmission under the tunnel cover.
All exhaust will need to be fabricated. Connection to the gauges will be fabricated, and a convertor for the speedo in particular. If your truck has a factory tach, that will have be be replaced or otherwise electronically adjusted.
Radiator will be changed for a larger unit.
Yeah, it's all doable. The engine bay is certainly large enough to contain a 350.
