Chevrolet Titan 90 ‘1970

In 1970, Chevrolet’s big news vehicle turned out to be the Titan tilt-cab highway tractor. Fitting into the new Series 90 designation, these highway monsters were designed strictly for long-haul work, and the majority were turned out with aluminum sleeper cabs.

Cab trim was aimed at the owner-operator, and included such options as wrap-around instrumentation, air-ride seat, three and four color custom paint schemes, and just about any other option that could be found on more expensive trucks of this type. Ratings were up to 50,500 for gross vehicle weight and 78,000 gross combined weight.

Most power was by Detroit Diesels (from 6-71N to 12V-71N) or Cummins engine (from NH230 to V903) ranging from 201 to 390 hp. Wheelbases ran from a shortie two-axle job of 92 inches to an extra-long three-axle straight unit of 235 inches.

All tilt cabs operated by a hydraulic mechanism which would allow the cab to be tilted and stopped at any angle up to 90-degrees. Both mechanical and hydraulic latches prevented accidental tilting. The BBC measurement for the standard cab was 54 inches. A 74-inch BBC sleeper cab was available with a 23″-wide bunk and 86-inch BBC with 32″ or 36″ bunks.

Little known was the fact that Titan chassis were produced in forward-control style for use as interstate bus chassis with wheelbase of 172 or 254 inches. The designation for two-axle models was FB90, FC90, FH90, FI90, FN90; for three-axle models – DB90, DC90, DH90, DI90, DN90 and DP90.

Newly available for 1977 was the Caterpillar 3406 direct injection engine. It was available in 280, 305 and 340 hp ratings, turbocharged for maximum power. Series designation had been changed for 1979. F90 (single-axle) trucks and D90 (tandem axle) trucks all now was identified as D90 Series trucks. In 1980, all Titan’s received massive grille from the Deluxe version Titan SS.
