I was wondering if changing the secondary rods on my LG4 would do anything to help me out. The motor is all stock and ran a 16.3 just with 3.73 gears. Its in an 83 T/A. THX

Rods & hangers will probably help. But, the stock LG4 air cleaner is a restriction that should be eliminated first.

Check out the tech article at https://www.thirdgen.org/newdesign/tech/quadrajet.shtml for more details on the tuning.
