’69 PLYMOUTH MUSCLECARS

Plymouth, like its brand-mate, Dodge carried over most of its high-performance models and 340, 383, 440 and 426 Street Hemi engines for the 1969 model year. For increased durability on drag strips, “A33 Track Pack” and “A34 Super Track Pack” options with 9 ¾-inch Dana Sure-Grip rears were available for four-speed high-performance cars without AC.

The highest profile ’69 PLYMOUTH MUSCLECARS were the Road Runner and GTX, available with engines up to and including the 426/425 Street Hemi. However, Plymouth, like Dodge, ushered in 1969 ½ with a tri-power 440 Wedge engine option, ideally suited for maximum street performance. Introduced in late-1969 and carried over for 1970 models, the tri-power 440 Wedge, right, was designed to offer the enthusiast an alternative to the heavier, more expensive 426 Street Hemi for competing against the hottest models from Ford, Chevy and Pontiac.

Plymouth’s 440 6 BBL boasted new-design 10.5-to-1 compression pistons and an all-new induction system featuring three two-barrel Holley carburetors on an aluminum high-rise manifold cast by Edelbrock. The two outer carburetors were vacuum-controlled. After initial production, Chrysler took over manufacturing the intake manifold and it carried Mopar #3412048. Output was 390 horsepower at 4,700 rpm and 390 pound-feet torque at 3,200 rpm. Plymouth branded this option 6 BBL, while Dodge promoted it as Six-Pack. An Air Grabber (#N96) option was available to duct fresh air directly to the air cleaner which was sealed to the hood. Fresh air induction was controlled by a lever – Carb Air – under the dash

Mopar factory drag racers campaigned both 426 Hemi and tri-power 440 Wedge cars throughout the 1969 season. Photos here of Dan Grotheer’s Plymouth powered by the 440/390 Wedge were taken in 1969 at the Chrysler Proving Ground, Chelsea, MI.
