I have 71' C20 with a 350 sb and unknown automatic trans. At its current condition it runs and drives fine but feels weak.

I wanna know what would be the best route. Ive heard that I can make my 350 more powerful as a 383 stroker but I have no idea how to go about this. I plan on taking it to a rebuilder but I want to know as much as possible before I take it in.

Or should I drop in a 454 bbc? If I do that what do I need to change? Trans, engine mounts, ???

I plan on towing and pulling a camper trailer..
