Lawrence, I assume that you are trying to get the motor under 305 cu.
in. for "D" Class. A cleaner and simpler method is to destroke the motor
with an offset grind. .020 destroke (calculating by the SCTA/BNI Rules
Book, Bore x Bore x 0.7854 x Stroke x # of Cylinders) makes it a 304.

 # of Cyls.     Bore    Stroke  Cu. Inches
    8          4.030    3.00    306.134 
    8          4.030    2.970   303.073 
    8          4.030    2.980   304.093
