Hi i was puzzled with the same problem when breaking in a new enigne, clutch would not engage even revved at a pretty high RPM, i have tried pretty much everyhting but problem persisted , i brought my car to a track and have a local expert looked at it. the clutch was properly set and all number looked decent. When i started leaning out, the problem magically improved to a point it was gone. Xray clutch is rather sensitive, so once you start to leaning out your engine then it will work out fine. You numbers look fine, just give it a try hope it helps
How many shims are used for the endplay. Shims located engine mainshaft and collet? Endplay very important on setting the clutch. Engagement of clutch depends on endplay and tension on spring and collar. Spring and collar adjust the engagement of clutch. Typical Centax clutch.
