How do you build an race engine to handle 8,000 rpm, night after night? You need a pretty trick setup. Zach Woods of Speedway Motors Racing Engines started with a Donovan 410 Block and a beautiful Callies Magnum XL crankshaft. You can see where this is going, all the way up to the Kinsler SBC Beast Injection Manifold. We were honored to build this engine for the National Sprint Car Hall of Fame and Museum.
