1970 OLDSMOBILE 442  Info:


  • All engines are 455's.
  • All Have 344... Fisher body tags.
  • If original front fenders are claimed, check the spacing between the two "4's" on the "442" emblems. The 4's should almost touch each other (very slight space, about 1/8") while the middle "4" and the "2" have a little larger space between them.
  • If the fenders are original they will be flat on the inner edge where the hood sits. '71-'72 fenders have bumps every several inches or so. Both should have red inner fenders and two braces just behind them.
  • If the car is a four speed, it should not have power brakes.
  • For a 442 convertible only, it was based on the Supreme body style.

Few exterior changes except for a unique grille made of vertical black rectangles, fenders, rear quarters, trunk lid and both bumpers. The 400 was replaced by the 455. The W-31 option was continued in the F-85 and Cutlass S, these cars were easily identified by W-31 identification on the front fender striping. New option was offered on the F-85 and Cutlass S called the Rallye 350. The Rallye 350 used the 350cu in. 310 hp engine and came in Sebring Yellow with orange and black decal hood patches and side trim. A rear deck spoiler was available on the Rallye 350, 442 and W models. The 70-72 442 wings were fiberglass, not aluminum. The W-25 OAI fiberglass hood was optional for all Cutlass variations.
