Do you want "more torque" as in LOTS more, e.g. a 383 or even a 455 or do you want more torque as in what your 350 would deliver if brand new Are you building a hot rod or just a good reliable truck that will perform as new?
Once you get past that question your answer should be evident. I am personally more into the good reliable truck end of things but your mileage (and torque) may vary depending on your wishes. Good luck and let us know what you decide. Welcome to the forum.

My '93 started life with a 305 and somewhere along the way acquired a 350 replacement. It is a solid truck with plenty of power for day to day use and a pretty tall rear end gear for reasonable economy. I expect if you went up to a GM crate 350 you would be pretty happy. I do not know the details of the swap as mine was done by a previous owner. The only major thing I have had done is have the transmission rebuilt.

My favorite "rule of thumb" is that a truck will run forever if two payments a year are spent on it. In your case two payments on a new truck would come pretty close to replacing your motor.

A running parts truck would be your cheapest/easiest route. Maybe something with severe body rot or involved in an accident. Possibly ask a junkyard if you can buy a whole truck from them knowing it will be brought back after your done minus the engine and accessories.

Agree with superdave, L31 R code 5.7L Vortec crate engine from Summit or Jeg's can be found for ~$1800-2000 with free shipping usually. Camshaft part number 14097395. Your 305 accessories should fit, intake might need to be port matched and definitely use the improved fuel spider assembly.
