For 1997 Dodge went all-out for racing the Viper V10 sports car, with their GTS-R version featuring aluminum block, heads and 13:1 forged pistons, Carillo steel rods and titanium valves with Isky roller lifters.

A dry-sump oiling system was used. Induction system consists of 10 individual throttle bodies from TWM, featuring top-feed injectors with nominal fuel pressures ranging from 55 to 115 PSI. Equal-length 32-inch headers snake out of the exhaust ports dumping into 4-inch outlets, providing an distinctive exhaust tone unique to a V10-cylinder powerplant, all done by Caldwell Development, Inc., Vista, CA. The ultimate Viper race engine!
