421-Inch Small-Block Makes 839 HP on Port Injection Nitrous Hit!
Done right, nitrous oxide can add a lot of performance to your engine. To see what it can do we head to Westech to see a 421 small-block Chevy dyno tested.

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!

421 SUPER DUTY ON THE DYNO @ Butler Performance!! This 421 SD is using the early "306" heads. These flow a little less than the 1962/ #127's and much less than the 1963/ #980 heads, but it still made great power. Almost 500 HP and well over 500 ft.lbs. of torque!! We actually have both a 1962 389 SD with #127 heads and 1963 421 SD with #980 heads in the shop now that we'll be finishing soon. We love working on these old, rare SD's and really love to hear them scream on the dyno! #ButlerPerforman
