Here are a few race cars from the same event.
J. Fleenor's 67 Nova with a 434ci small block and NOS ran high 8's and was a True Street competitor.
R. Tumbry's 68 Nova with a big block is a 9 second street car. This car has been featured in Super Chevy and RPM magazine.
C. Myer's 70 Malibu was another True Street competitor that ran high 9's. I'm not sure what it had for motivation.
This Z/24 had an ex Richard Childress Racing SB2 in it with a Lenco and ran 7.80's. Pretty quick for a naturally aspirated small block.
J. Burns' 72 Rallye Nova with a 598 ran mid 9's. You don't see many Rallye Nova's anymore.
J. Robinson's 71 Z/28 had a 540 and was another mid 9 second street car. This is the "Papa John's" car.
The McGee's 66 Chevy II is one of my favorite second gens. It has a naturally aspirated 406 and runs high 9's in street trim. This car was featured in the Nova annual that Super Chevy puts out.
Nice 63 Chevy II sedan with a big block that ran high 9's.
