KUHNS ADDING SONNY LEONARD SEMI-HEMI HEADS

West Coast Pro Mod racer Kirk Kuhns supposedly will have a 526 ci Sonny Leonard Semi-Hemi in the Viper he qualified at Chicago last weekend.

Troy Coughlin's NMCA Pro Streeter will have an 815 cubic inch Sonny Leonard engine under the hood of the team's Cavalier. One of the Agent's operatives was in Leonard's Lynchburg, Virginia shop when the engine was being dyno tested.

Interestingly, EFI wizard John Meany was on hand to personally oversee the installation of his new EFI program on the 815 ci Semi-Hemi Chevy. The Agent was sworn to secrecy but can tell you that the engine made way over 1700 hp (corrected) during the dyno session. (Jeff Burk photo) [6-17-2005]
