General Motors GMT360 platform sport utilities, the Chevrolet TrailBlazer, GMC Envoy, and Oldsmobile Bravada, were designed to have distinct personalities. But GM’s new all-alloy Vortec 4200 inline six truck engine would be the same, whether you order the Chevy, the GMC, or the Olds. That’s a good thing.
“Quite” and “smooth” don’t begin to describe how good this powerplant felt at idle or at wide open throttle. In fact, with ratings of 270 hp and 275 lb-ft, the straight six served up better numbers than any small or medium size V8 sold in North America, at the time, with the exception of GM’s own Vortec 5300.
