Looking for Big Block power with great drivability, here it is. We took Chevrolet Performance's cast iron 502cid 450HP and installed the Holley Sniper EFI system along with all the other components needed to complete this engine. Say good bye to tuning and rebuilding carburetors and hot and/or cold drivability problems. The Holley Sniper EFI fuel injection system is self tuning according to your driving habits and insures you'll get the most out of your big block Chevy.
