| 1937 PACKARD TWELVE HAS TOCCO-HARDENED CRANKSHAFT The advanced 1937 Packard Twelve—one of the world’s leading automobiles—is mechanically far ahead of any car that has ever borne that distinguished name. Its V-12 engine, like the new 1937 Packard Super-Eight, has a TOCCO-hardened crankshaft — a superlative endorsement of the TOCCO PROCESS. The Packard Motor Car Company has adopted TOCCO-hardened crankshafts for the engines of its finest 1937 cars—the Packard Twelve and the Packard Super-Eight. These new, deluxe cars, listing at the factory from $2,335 to $3,420 and up, represent the last word in Packard’s experienced engineering—the best cars that money can buy! In them nothing has been overlooked which will help give “the Man Who Owns One” a superlative measure of luxurious transportation, long, trouble-free engine life and economical service. Packard engineers say that the TOCCO-hardened crankshafts in these fine passenger-car engines will give Packard owners not only longer-lived bearings but more efficient operation and lower oil and other maintenance costs. Undoubtedly Packard, which has pioneered so many engineering advances, is but the first of a long list of passenger-car manufacturers who by adopting TOCCO-hardened crankshafts will give their owners improved engines, smoother power and lowered costs. A MASTERPIECE OF ENGINEERING. The Packard Twelve-cylinder engine is looked upon as one of the world's leading power plants. All Packard Twelve and Super-Eight engines now have TOCCO-hardened shafts. | ||
