1981 mods
Just bought 1981 4 speed with with orig block, aftermarket heads, intake and 4bbl Weber carb. Cat converter not used, straight pipes to mufflers. Car runs strong, no blue smoke at start up or when driving. No codes observed on dash. Opinions on Weber vs. replacing with Qjet. And replacing cat and original pipes.

Leave it as is. Original q-jet is computer controlled. If the PO has changed the cam as well then it may not work as intended. If you still have the original cam then you will be spending $$ for a fuel economy gain.
