Handed out a club card to a guy who had his 383 SBC on the dyno breaking it in and checking numbers. Was a blueprint crate engine with aluminum heads and a tunnel ram with 2 500 eddies on it. Motor made 427 horse and 470 torque. Is going into a 72 chevelle. His buddy that was with him also had a 72 chevelle with a 454 in it. They were from Winstead area I believe they said. Is always fun to watch things on the dyno and hear the roar.
