Before pulling the engine I'd check to make sure the carb is the right size. The bore should be the same as the manifold opening. As far as I know 250's and smaller use a smaller bored carb on the same manifold. Whatever the manifold opening is should be the same as the carb. I remember from a 67 1 ton that a 292 should make good power with lots of torque.

Also before pulling the engine I'd try running some cleaner or water through it to clean up the deposits. I pulled a 250 and found out later it had stuck rings which could have been freed up quite easily. I'm not regretting the 350 though except for all the lost time where I could have been doing something more productive.
