this is rare, and very cool... a 442 without a 4 barrel. Why the hell did they do that? THAT is what a 442 is ABOUT! Four barrel, 4 speed, dual exhaust. Am I wrong? Anyway, check out this cool 66 with Hurst rims! Looks great!

In 1966, Oldsmobile offered the L69 option to compete with the tri power GTO. 

The 6-bbl Olds horsepower matched the GTO’s. Because the GTO had such great marketing and advertising, only 2,129 Oldsmobiles were ordered with triple two-barrel carburetors (and 1,171 of those were Cutlass Holiday Coupes)
