I would probably swap out the carb first and see how that works. The quadrajet is a great carb and would work nicely if you get the smaller CFM one. Edelbrock makes new versions of them for a decent price. If they are set-up right and not over jetted they are truly the best for these trucks.
And if you can't find a stock manifold you can go with an Edlebrock performer (not the RPM model). Even if you have to paint it to make it look more stock. Then after all that see how it goes. Unless you are doing a lot of long trips that set-up should be fine. And if you decide to sell the old auto trans let me know..........Ed.
