1966 Pontiac GTO Rear View Drivers Side
John Coursey relied on a set of 10.5-inch M/T ET Streets to get the 462's power down at Raceway Park. The bang of the Goat's powershifts bouncing off of the retaining walls and echoing down the track was pure heaven. This guy gives no quarter to his restored Poncho!

A YH-code '73 455 block was built with internal goodies like forged SRP pistons and ported 6X heads with Ferrea valves. Externally, it was personalized with classy Edelbrock valve covers and anair cleaner assembly. MSD's 6AL ignition box helps the Pro Billet distributor give the 462 a nasty jolt.

A broken posi affected the ET, and a malfunctioning carb hurt the mph, but the Taylor-built mill still had the grunt to pull Coursey to low 13-second runs at over 100 mph. John was dropping the clutch at 3500, shifting at 5200, and flying through the traps at just over 5200 rpm.

John Coursey is now reliving the memory of the '66 Goat he owned at age 16, and building a few memories with his teenaged son Chase, who has contributed greatly to the project and stands to inherit this work of art one day. Lucky kid.

1966 Pontiac GTO Front View
Here's one of the main reasons why this Pontiac causes fisticuffs at shows: John couldn't live without a few items from a '67 Goat that he was able to pick up 'real cheap,' so he mounted them on the '66. The grille, the entire nose panel and grille surrounds and the rocker moldings have apparently caused enough quizzical looks to fill a blooper reel.
