14.  ENGINE: Iron blocks only –  NO aluminum blocks.  Any head allowed.  Engine can be maximum size of 360 cubic inches plus 1% maximum displacement.  (360 + 1% = 363.6).  Engine cubic inches will be checked with a cubic inch tester.  Double-X Speedway track officials reserve the right to check any engine at any time.  If driver and/or owner does not allow the engine to be checked, it will be automatically considered illegal.  If driver and/or owner believes the cubic inch tester to be wrong, he/she has the right to remove the heads to prove its legality.  If the engine tests legal, the track promoter will pay UP TO $100 for head and manifold gasket replacement.  Driver and/or owner will forfeit all money and points for that race night and may be subject to suspension if the engine is proven illegal.


15. PROTEST: Any driver in the feature race, finishing on the lead lap will have the right to protest any engine competing in the same event who is also on the lead lap.  DRIVER only, making the protest must post $300 cash with a designated track official or Promoter within 5 minutes of the feature race to make the protest legal.  If protested engine is found to be legal, the driver making the protest will lose the $300.  If protested engine is proven to be illegal the $300 will be returned to the protestor.  If driver and/or owner refuse inspection or is found to have an illegal car, he will lose all points, money, and trophies won that night and may be suspended for two (2) race nights.  Protester AND his car (BOTH) must be off the track in order to make a protest!!  This means DO NOT stop on the track to file a protest, it will not be honored.  NOTE: if the proper equipment is on hand, and inspector is available, time permits, and/or circumstances allow, a driver or owner may request that the cubic inch size of their engine be tested for legality while the engine is cool IF the cubic inch size of the engine has been tested while cool and has been proven legal, a driver/owner may avoid a “tear-down” that night for the purpose of checking cubic inch size.  However, this remains at the discretion of the promoter and/or inspector.
