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

1971 Firebird with Butler Pontiac 435 c.i. Supercharged combo. Frank Naugle bought one of our ready-to-assemble Butler Pontiac Builder Kits that he built himself. We started a 400 block and added billet, four bolt main caps, and one of our boost capable 435 in. stroker kits (4.00” stroke). This kit included a Butler/COMP hydraulic roller cam kit and our Edelbrock heads with matching Hurricane low profile intake. Frank finished it off with a torque storm complete bolt-on supercharger kit. Awesome
