Just a modest engine meant to go into the Grocery getter that the family can get some use from. I mean what person would not want to get 630 Horsepower with 631 ft. pounds of Torque out of this Pontiac 400. Just put this engine in the everyday driver and see the looks on the kids faces when you hammer down and show them what True American Muscle can do. As long as you do not look at the Gas Hand while driving then you will think this engine is perfect. This engine comes equipped with a Forged 4.250 stoke crank and Forged rods with ARP bolt upgrade. Topped off with a Holley 950 Ultra XP to make sure you get enough air and fuel to make this engine purr. Of course you have to keep it looking sleek with our Black BP Short Valve Covers that will still fit most 1.65 Ratio Rockers underneath. This way you do not have to compromise looks for functionality which is what Butler Performance strives for in all aspects of our builds.
