With Ford factory participation gone, and generic Ilmore engines optional for all makes, will the NASCAR truck series survive? Toyota has long said they will not allow non-Toyota engines in their sponsored vehicles, so their participation in the series is questionable. At best, I'm guessing it will become an all-Chevy series, with a few Ilmore-powered Toyota and Ford bodies run by independents until the supply of sheet metal dries up. Since the spec-engine is promoted as being cheaper than the manufacturer approved design, most of the Chevys will probably use the spec engine. Seeing all the empty seats the past few years, I see nothing in the near future that will pay the purses, much less draw new sponsorships. If the series folds, what would that do to the remaining NASCAR series that are double-billed at many tracks?
