I have noticed that the SPG rules you have to run the stock flywheel but timing is non tech. I have read that the box stock timing is around 26 degrees out of the box. It seems all the CL cams state timing should be 32 degrees. Since the CL cams are legal is that why they made the timing a non tech so you could get the use out of the cam. Still trying to get a set of rules for the new track here. One of other tracks that we are looking at about the same rules says stock flywheel with stock key. They do allow the CL cams there. Thanks
