The second evolution of the Excalibur was introduced for 1970. Known as the Series II, or SII, these cars received a bespoke chassis, as well as various components like the brakes and suspension from a Corvette. In addition to mechanical improvements, the Excalibur gained a raft of luxuries and equipment, making it a more complete package. Notably, a 350ci V8 became the new standard engine, while a 454ci V8 was optional. Bot manual and automatic transmissions were available. Production of the Series II Excalibur ended in 1974, before being replaced by the Series III Excalibur.
