I prefer the SS1s/Magnums on all Cutlass'/442s. '71 was the first year for the body color painted SS wheels.
The W30s received the blue printed/ hand assembled factory engines in '71, as well. The cam timing was revised along with the compression drop to maintain the W30s status as one of the premier performers for the '71 Model year.
Some of the Special W30 equipment Included the "H" heads mentioned, Mandatory ram air/OAI set up,an aluminum intake, specific distributor, specific coded auto transmition and rear axle housing. Along with the signature red inner fender wells.
This one also has:
Power Windows
Power Door Locks/Added
Power Disk Brakes
Power Steering
Sport/Tilt Wheel
Cruise Control/Added
Hurst Dual Gate Shifter
A/C /added
Power Trunk Release/Added
Rally Pac/Gauges
W27 Aluminum rear end cover
AM/FM with underdash eight track player
Aux. lighting group
Internal Hood Lock
This car is great for cruising and runs well on premium pump gas. It also has a tremendous amount of torque
