If it’s still running points, swap in a performance curved electronic ignition. Find the ideal timing vs. just setting by the book. Ensure the existing 2-barrel is dialed in, meaning a/f ratio is where it should be, not too lean, and that the accelerator pump shot is properly adjusted. Then swap in a 3.55 gear (at a minimum or a 3.91) And if the trans is in good condition install a Trango TF1 or TF2 shift kit in it. Install better or best flowing mufflers depending on what’s currently on it. Dynomax are a good choice.
