The revised body style and increased performance resulted in the 4-4-2 being awarded pace car duties at the Indianapolis 500 race in 1970. Those seeking to experience the ultimate in performance from Lansing could order a "W-Machine" version of the 4-4-2, dubbed the W-30 package. The 4-4-2 W-30 added a fiberglass hood (option W25) with functional air scoops and low-restriction air cleaner, aluminum intake manifold, special camshaft, cylinder heads, distributor, and carburetor. Two W-30 equipped 4-4-2 Vista Cruisers were produced by special order. Rear shoulder seat belts were optional at $23.
