Chevrolet's largest engine ever produced from the factory was the LS7 454, a big block powerplant that came in 1970. The raw power of these engines gave inspiration to builders of street cars ever since, including this highly-modifed 800-horsepower Pro Street example!

Fitted with a BDS 8-71 supercharger and dual 850-cfm Holley four-barrels, high-lift roller camshaft and forged pistons, this radical competition-built 454 has all the necessary ingredients for all-out performance all the while being streetable. Aluminum cylinder heads with 2.25-inch intake valves pull in the massive air intake, with 2 1/4-inch exhaust headers expelling the spent exhaust fumes. Wild!
