Test N Tune Invitational Track Day at Hallet Road Course near Tulsa, OK on 08/07/2011. ERA 745 is a 1965 Shelby Cobra 427 S/C replica built in 2007. On this weekend, 25 drivers got together and rented the track for 2 days. Several Cobras, vintage Mustangs, GT40, 63 Corvette Grand Sport, and an Indy racer. This Cobra has a Keith Craft aluminum 427 side oiler, stroked to 482, putting out 580 HP at the flywheel. Trans is a TKO-600, tires are 15″ Goodyear Billboards vintage replica bias ply. Problems are evident with the 2-3 upshift at WOT – double clutching not in my skill set Best lap time this day was 1:30.4, running the course in reverse (clockwise). Enjoy!
