The ultimate American land yacht—a full-size sedan and wagon that was the last of the rear-drive, V8-powered B-body cars. It was a massive, comfortable, and powerful car that was a throwback to the glory days.
The Roadmaster was a front-engine, rear-drive, body-on-frame full-size sedan and wagon on the GM B-body platform. It had a 5.7L LT1 V8 (260 hp) and a 4-speed auto (4L60E). It was massive—over 5.5 meters long.
The Roadmaster is reliable. The LT1 V8 is a great engine—it’s a pushrod V8, simple and reliable. The 4L60E is a good transmission but needs regular maintenance. The Opti-Spark distributor is the Achilles’ heel—it fails when it gets wet. The Roadmaster is a reliable classic.
