Back in the 70's I took my wifes 65 Valiant to the track just for S&G'S. 4 dr sdn 170 engine 904 trans. 1st pass was 22.8. Did some tweeking at the track. Biggest thing was the throttle linkage adjustment (only opening about 2/3's) Loosened fan belt, removed PS belt, installed bigger jet in carb, played with timing. Best that day was 18.9
Couple years later that drivetrain (legal NHRA Z/SA) wound up in a 1965 model 100 2dn sdn at 2530 lbs, and ran a best of 16.2
