You don't hear from engine builders very often, so we got one on this edition of the SprintCarunlimited.com Deep Dive. Adam Cofer recently purchased Ott Racing Engines from Don Ott in central Pennsylvania, and he came on the show to discuss a variety of topics. They include the reason it takes longer to get engines, the rising cost of engines over the years, exclusive deals, is a spec 410 engine viable, the state of the sport, and much more.
