The goal was to make more power from a 406 c.i. Small Block Chevy engine running on pump gas. Jeff Smith from Car Craft writes about how he and his crew did just that, picking up more than 500 lb.-ft. of torque and more than 60 horsepower with the use of a COMP Cams Thumpr™ Cam, Pro Magnum Lifters™, 1.6:1 Roller Rockers, Pushrods and 10W-30 Muscle Car & Street Rod Engine Oil. We invite you to purchase the December 2011 issue of Car Craft.
