The soft garnet red cloth seats and red interior with black trim, black steering wheel and vents makes this not only a confortable ride but looks tough too.

A Little history
The base Model was first introduced in 1936 and by 1990 was selling more than a half a million units a year. up through the years the truck came in either two or 4 wheel drive and both versions came with either a six-and-a-half-foot box or an eight-foot-box.

Trucks like the 454 SS shown above were produced from 1990-1993. Total number of units produced was 16,953 its best year in 1990 with a total of 13,748 units sold, that left a total of 3205 sold from 91-93. The 454 SS had reduced payload capacity smaller than the standard models in the years before, a high sticker price-(Most buyers forget about the high price after sitting behind the wheel) and only gets at best 10mpg-12mpg

The 454 SS was and still is a pure thrill machine. Stock models are good for mid to high 15 second range in the quarter mile times. Its mid range punch is even better. The 454 SS was manufactured and assembled at only one General motors plant located in Fort Wayne, Indiana

Ever think about running natural gas in your 454 SS engine?
To validate the changes/modifications by Tecogen to a naturally aspirated Chevrolet 454ci natural gas fueled engine. The application is static, constant speed, perhaps power generation for peak load shaving. The engine was performance tested and durability tested until failure occurred at 1,794 hours. The engine experienced numerous problems which included high intake and exhaust valve recession, intake and exhaust valve spring failures, valve spring shield breakage, cracked exhaust valves and cracked pistons. Overall this engine did not perform well, but has the potential to achieve a design goal of 2,000 hours at 3,600 r.p.m. through proper engineering analysis and design.
