R5P7 fresh off the dyno. Made 800+ uncorrected hp. This engine has all the nascar pieces. Bryant, Carillo, Jesel, etc. The difference is we bumped the compression up to 13.7-1 and has a little more camshaft. This one has .937 keyway lifters. Built by Mike Duke (MDR). For complete details you can contact me. Will be complete as you see it in the pics.
