Performance Engineering was run by Dave Billes, a member of the well-known Canadian Tire family of stores, originally mostly auto parts and tire related, but now much more than that. Lots of stores everywhere in Canada. Dave is a member of the Canadian Motorsports Hall of Fame. He was a Corvette racer in the early sixties, before opening his shop in Barrie Ontario (about an hour's drive north of Toronto).
He sponsored a Can-Am car run by John Cordts and later a CART Indy car for Jacque Villeneuve (the "Uncle") under the Canadian Tire umbrella. Some othe family members also went drag racing.
Performance Engineering was probably the best known Canadian engine prep shop in those days. I believe it is still operating. Gord Chance worked for Dave at one time and later opened his own business known as CRM Gord later moved to CA with his engine prep business.
