To qualify for Rookie of the Year, the driver must compete in at least 75% of the scheduled events and have filled in rookie box on registration form. The rookie winner will be determined by how many total points they accumulate through out the season. If there is a tie the winner will be determined by most wins, seconds and so forth.  

 1.)   ENGINE

A) NO aluminum blocks or titanium engine parts are allowed.

B) All engine casting numbers stamped on the engine will be left on the block at the bell housing area.

The following MSD #’s are    allowed: P/N 8728, MSD Soft Touch Rev Control, is designed to be used on             standard points ignition or inductive ignition systems. This means that the             PN8728 can be installed on engines with a GM HEI Ignition, Ford or Chrysler       electronic ignition and any standard breaker points system (No MSD box    needed), P/N 8738, MSD Soft Touch Rev Control for use with the MSD 6T and      6TN Ignition Boxes, and P/N 6420, MSD 6AL Ignition Control Box w/ Rev Limiter Built-In, P/N 6430, MSD 6 ALN Ignition Control Box w/ Rev Limiter Built-In.

III. Engine Rule

Note: Recommendation for all classes with compression limits: During any future head removal or rebuilds of your engine, please have 2 adjacent head bolts on the right and left head drilled with a 1/8^th inch hole for safety wiring and sealing. If you should happen to be teched at the track as part of our normal inspection process and you passed, this will allow us to “seal” your engine. As long as the seals are place and not tampered with, we will know that engine is legal by removing the valve cover. We’d also like you to have 2 adjacent intake bolts on the right and left sides drilled for the same purpose. Our Tech Inspectors will be willing to come to your shop to “pre-tech” your engine subject to time and availability.  If the inspector “pre-techs” your engine at your home, shop or engine builder’s there will be a least a $50 fee, payable to the inspector to compensate them for their time and travel. When the inspector arrives you should be ready to finish assembling your engine. You must have one cylinder head and the oil pan off the engine. Two adjacent head bolts (for each head), two adjacent intake bolts and two adjacent oil pan bolts should be drilled with 1/8^th holes for the safety wire to pass through. The inspector will expect you to finish assembling the engine after the proper checks have been made. This pre-tech option is highly recommended. We as tech inspectors encourage this to help minimize at track tear downs and protest. Please exercise this option if you can.   Call John Fern (402-984-6329) if you have questions.

A)      Engines must have the following specified stroke: GM 3.48”, Ford 3.50” and Mopar 3.578”. The maximum bore for any engine is 4.060”. Crank and rod assy. must be steel.

Failure to report directly to claim area will result in disqualification and loss of money and points for that night of racing (engine is still claimable). In case of multiple claims on the same engine, a drawing will be held to determine which driver gets the engine. Should the first eligible driver withdraw his claim, he will receive a $200 fine and the next qualified driver will be awarded the engine. The claim is not charged to those not awarded the claim.
