1966 Pontiac Tempest
The successful LeMans/Tempest saw relatively little change for 1966 with the exception of smoother contours, including hopped-up "Coke-bottle" rear fenders and, on coupes and hardtops, "flying buttress" rear roof pillars astride recessed backlights. The Sprint package was available to order on Tempest, Tempest Custom or LeMans. Along with a bigger 6 cylinder engine featuring 207hp and a Quadrajet 4-bbl, the package comes with a chromed low-restriction air cleaner, dressy cam cover, synchro 3-speed with a Hurst floor shifter, sports striping and special emblems.1966 Pontiac Tempest Specifications & Production Numbers
