Pro Stock Competitors;

Effective for Pomona, CA Lucas Oil NHRA Winternationals, March 30, 2023, all Pro Stock entries are required to run Holley coil Part # 556-112 without exceptions. The required coils are of "large body" design and no other coil will be accepted. We understand that during covid there may have been supply chain issues that enabled replacement bodies that are not the large body 556-112. There is plenty of 556-112 "large body" coils available from Holley at this time and will be required by the date mentioned above. The discovery of any coil other than the Holley 556-112 "large body" will result in disqualification and/or further disciplinary action.
