ADDITIONAL RULES CHANGES FOR 2006 ANNOUNCED FOR GRANDVIEW SPEEDWAY RACERSGrandview PR
BECHTELSVILLE, PA NOVEMBER 5, 2005 . . .Continuing their efforts to control the increasing costs of racing and wanting to be sure all the racers are ?playing on a level playing field? Grandview Speedway has announced additional rule changes for the 2006 season.
?Mike Kelly has been working with racers and engine builders as he continues to polish the rules for 2006,? said track owner Bruce Rogers. ?He has listened to their input and that has helped us immensely in creating rules that we feel will best serve the racers at Grandview Speedway.?
For the Late Models in 2006 all 2005 engine rules will apply. The only exception will be that a maximum compression ratio allowed will be 10.5 to 1. There will be NO aluminum, Ford N, or Chevy LS-1 HEADS allowed in competition.
For the NASCAR Modifieds current 2005 rules for the cast iron head ?9 to 1? engine will be enforced except for carburetion. The current 650CFM or the optional 750CFM HolleyHP Series #0-80535-1 or #4779 (with current acceptable modifications) will be permitted on engines using the following cylinder heads: Chevrolet with 23 degree valve angle, Ford with 20 degree valve angle and Mopar with 18 degree valve angle. All others will use the current 650CFM carburetor.
ENGINE INSPECTIONS will take place on a random basis. Officials may request removal of an intake manifold, cylinder head or oil pan of any engine at any time. Any engine violations will incur the loss of ALL MONEY for the race event and a point?s penalty. A second offense will include indefinite suspension. An engine inspection will be required before a suspended racer is reinstated.
The carburetor size with the Brodix Spec Head is to be determined.
