Chevrolet 454SS


Chevrolet 454SS

With fuel concerns diminishing in the mid-1980s, manufacturers began to produce more powerful cars again and with America's pick-up obsession, a new market was soon born: the muscle truck. Chevrolet, having long been a maker Of pick-ups, was one of the first to get a grip on the market with their 1989 454 C1500 truck, which had been re-styled just a year before, so looked bang up to date. Underneath the SS454 was still very trucklike, with a strong ladder frame chassis and carlike double wishbone suspension, but a leaf spring rear. All spring rates were uprated and Bilstein shocks took place of the stock ones. Also modified was Hie steering, with quicker gearing to help the handling. The 454ci (7.4-liter) came from the standard C/K 3/4 and 1-ton pick-ups, and with its long stroke was designed for low rpm torque delivery. Rear end 4.10:1 gears were good for rapid acceleration.
