We are building this engine for a good customer of ours for a 57 Chevy street car. We started with a Dart Block and added a Scat Rotating Assembly. Next is a Crower Hydraulic Roller Cam and a set of Brodix Heads top that off with a B & M 471 Supercharger and get ready to peg the fun meter! Check out our Facebook page for the Dyno video coming soon. Thanks for your support!
