Here is a cool little video of a 421” SB2 headed engine we freshened/updated on the dyno today. It ended up making just over 880 bracket friendly horsepower! Thank you to the Marcum family for making the trip from West Virginia and trusting us with your engine needs! | Sunset Performance Engines LLC
