Nelson Racing builds a 427-inch stroker for a customer’s 1955 Chevy show car. With a solid-roller valvetrain, and the right parts, this big-inch small-block Chevy made over 600 hp on Westech’s dyno.

If you want budget-friendly power for your Chevy or other hot rod project then it’s hard to beat the time-tested small-block Chevy engine. This time we test a stock-looking pump gas 383 SBC.
