Q-Jets are awesome. Why spend $$ on something just because? If you have $$ to burn, there are a lot of other things you can get to freshen the truck up.

The stocker the better and the more reliable. Unless you are building a street machine with a 11.5:1 bottom end for the street, leave the motor alone, maybe upgrade to HEI and install a taller K&N that raises the lid of the air cleaner about 1/2".

Exhaust recommendation: Leave the manifolds, but go with a 2-1/2" exhaust and a cross over pipe.
