I would really be interested in knowing what was the quickest time a legal '66 GTO Stocker ever ran, in national NHRA competition, who sponsored the car, who built it, & who drove it.
Would also like to know what year the last SERIOUS '66 Tri-Power GTO Stocker raced, in national NHRA competition.
I'm not aware of any that have run this century.
May not have been any since the late '60's or early '70's, since there have been so many later model Pontiac combos that were more competitive.
Unless a '66 GTO would show up on some win list or nat record list, I don't know how you'd ever find the info I'm talkin about.
I'll ask on a couple of Pontiac sites I'm on & see if anybody has any related info.
