We love building sleepers, so why not a sleeper engine? We're building a big torque, big horsepower, pump gas 534 cubic inch Big Block Chevy disguised as an old school stock engine. This build uses a host of high-tech aftermarket pieces, but it's designed to swap into anything that a big block will fit into. We go from a table full of parts to a full-blown dyno session to see what it cranks out.

WIN THIS ENGINE!
Enter the UEM's Big Block Powerhouse Giveaway for your chance to own this sweet sleeper. Giveaway ends March 10, 2026
