Roger Bolliger's SCCA Road Race Trans Am
Roger purchased a Butler Performance ALL ALUMINUM traditional Pontiac engine, dyno tested/tuned and delivered to him in Switzerland. His engine is 496 cu.in. based on our IAII/Butler Performance aluminum block and using our std. port Edel. Heads. It made over 690 HP on pump gas with the built-in durability to take continuous abuse on the road course's of Europe. Even though Roger is thousands of miles away, he relies on Butler Performance for all his high performance Pontiac needs.
