Victor Santos had a strong 3rd gen, which now belongs to Bill Kennedy. It qualified near the top of a lot of div 1 race Q-lists. I think this fact is interesting. Vic was #3 at the 1st New England Nats, in 2013, #2 in '14, & #1 in '15.

Steve Smith had a strong 3rd gen. It made the field at Indy, several times. In '09 it qualified @ #52, with a 1.13 under, 9.97.

It is now raced by Scott Burton. IIRC, it now has 428 power. At Indy this year, it ran an .844 under, 9.556, which was good enuff for #55.

Brad Burton also drives it some. He picked up his 1st Lucas Oil Series Super Stock win, last year.

The Lynn McCarty family has raced 2 GT cars. One is a 3rd gen. The other is a late model Grand Am, I think. I believe they've run both an SD455 & a 428. At Indy this year, the GA was #76 @ .759 under.
Carroll Warling has a '74 GTO which he runs in GT. I think he runs a '74 400 in it. Not sure. He also now runs his '74 Lemans in GT. I think it now has an iron head 428 in it.
Long time Pontiac Stock racer Larry Maxwell now has a '68 Bird, which he runs in GT, with '74 350 Pontiac power.
Will work on the pics.
