The Mark IV big block was the culmination of Chevrolet's performance engine development. Introduced in 1970 and marketed under the previous “396” label in smaller cars and “Turbo-Jet 400” in full-size cars, the 402 powerplant terrorized local drag strips and gave high performance engines a new standard. The success was short lived due to fuel shortages and emission standards. But fear not! The horsepower happy big block lives on and Speedway Motors is your source for performance parts and accessories for your 402 Chevy engine.
