Sunflower Yellow Corvette with Black interior, 454/425hp, 4-speed manual transmission.If you were in the market for the ultimate Corvette in ’71, you needed to look no further than RPO LS6. Checking this $1,221 option on your order form gave you cast iron 454ci big block engine with aluminum heads, 850cfm Holley carb, A.I.R. smog pump, bolted up to either an M-22 close ratio “rock crusher” 4-speed manual transmission or M40 3-speed automatic.This engine produced 425hp and was second only to... the L88 as the most powerful engine ever offered in a Corvette up to that point! Developed by Zora Arkus-Duntov and his team, the plan was to design an engine for racing. But only 188 production versions were offered. Making it one of the rarest engines. Even rarer than an L88 and almost as powerful!All LS6’s are special. This one is just more so! The awesome example presented here has been frame off restored and is the recipient of multiple N.C.R.S. Top Flights, a Bloomington Gold, and Triple Diamond Award! The Sunflower Yellow exterior glows and more than fits the car’s character. Documentation includes the original Car Shipper and Dealer Invoice, as well as extensive photos of the restoration and receipts for the work done.
