The 454 big block is a true legend of an engine that has been the base for many of the fastest, highest HP builds in the history of hot rodding. A product of growing power needs for the bigger, heavier GM production cars and trucks of the 1970's - GM had to come up with something as successful as their small block Chevy platform. The 454 big block became the industry standard for high HP and torque curves, with a boatload of useable power and room to grow as the budget allowed. Even though the 454 big block has been around for many years, it is still a highly desired powerplant for many chasing after that unique big block tone and neck-breaking power! Speedway Motors has a multitude of performance aftermarket parts as well as OEM reproductions for any of your 454 big block needs!
