Re: 1970 Oldsmobile W30 Coupe 4 speed
So, in the case of the 1970 W-30 you got some mandatory options over and above a 442.
The W-30s were "select fit" factory blue printed 455 engine. Weights and clearence were checked and components were grouped and batched together for assembly.
Carb.
Dist.
Rear.
Had W-30 codes and specific part numbers.
Aluminum Intake
Special Heads
328 degree Cam (Only with 4 speed) manual disk brakes only
Dual sport mirrors
Red inner fender wells
Mandatory W-25 special OAI hood.
Less body and sound insulation was used as compared to a std 442.
The cams are so lopy on a 4 speed W-30 that some original owners as well as dealers thought the cars had issues.
