Since you are looking at the 220 HP 1966 283 in SS/LA a 13# class at 11.45 index. HP in the a Chevy II is 233. Stick HP is 237 or 52 lbs more. Now in a Chevelle , HP is 217 for the auto and 227 for the stick. A Chevelle can be 238 lbs lighter than a Chevy II with a auto and a 130 in a stick with the same index. In GT the hp is 233 auto and 230 for the stick. That is why Bick and Cassel run in GT rather than ss/k, they get to run 84 lighter. Big cars [Impalas] hp is 229 auto and 230 for a stick. Someday I would like a shot at the 9s in a Chevy II but in SS/JA 460 lbs lighter than L. Everybody stay safe and enjoy life as we know it. Tom
