The iconic W-Series big block engines from General Motors could always be spotted by the uniquely shaped heads and rocker covers for a distinctive appearance. Three different variations of the W-Series engines existed with the 348, 409, and 427 big block. The first introduced of the three was the “Turbo-Thrust” 348, intended for use in trucks and large passenger cars such as the Impala SS. Today, the 348 is still a highly sought after engine for restorers, rodders, and racers of all types. The folks here at Speedway Motors know what it takes to bring that old school big block back to life and you can be sure to find what you’re looking for with only the top brands and parts you need for your classic W-Series big block Chevy.
