The process begins with inserting the ring into the bore, and making sure it is square using a squaring tool to align it properly. A feeler gauge inserted into the ring gap will show you the existing dimension, and from there you can make your adjustments. For a street engine, multiplying your bore size by 0.004in will give you the top ring gap you are looking for.
004 x 4.00in bore = 0.016 inch ring gap For high performance engines, the multiplier changes to add more clearance, but the math stays the same:
Modified or Nitrous Oxide - 0.005in x 4.00in bore = 0.020 inch ring gap High Performance Racing - .0055in x 4.00in bore = 0.022 inch ring gap Racing with Nitrous/Turbo - 0.006in x 4.00in bore = 0.024 inch ring gap Racing Blower/Supercharger - 0.007 x 4.00in bore = 0.028 inch ring gap For the second ring, the process is the same, but with a slightly different gap, based on application:
Street - 0.005in x bore size Modified or Nitrous Oxide - 0.0055in x bore size High Performance Racing - 0.0053in x bore size Racing with Nitrous/Turbo - 0.0057in x bore size Racing Blower/Supercharger - 0.0063in x bore size According to wiseco I think you way out of spec ,your engine

The saga starts with the following message: Hey guys I have a decision to make. I know what you all will probably suggest and it will probably agree with me way down inside, but here it is.
