I STILL argue the lightest are the 60-62 Valiant and 62 Lancer.
there is a U tube of naturally aspired slant Lancer running at Mo Kan in Mo outrunning a hellcat 3 for 3 and time was what 10 seconds Yes that is 1/4 mi.... but it is a race prepped car and was not cheap to build no doubt, but shows what can be done?????
