This is a 1966 L69 442, very rare car, very fast car! In 1966 and 1967 only they had the big bore/short stroke 400, the L69 added Tri-Power!
I had a gold L69 in High School with the factory 3:90 gears and a 4 speed, I could spank my friends 1969 Hurst Olds (455) at will. With the stock
exhaust and G-70 tires and me driving it would run 13:80's all day long. In NHRA Stock Eliminator trim they run bottom 11 and high 10 times!
