While it may have been working for you, I just don't see how you can turn your motor or any motor 8000rpms with only 145 lbs. of spring pressure on the seat......that's the amount I run with a hydraulic flat tappet camshaft........

I don't have the cam card/specs with me right now, there are in the shop, but my last 2 solid roller camshafts, Comp and Lunati called for a minimum of 200 lbs. of spring pressure on the seat and I have a 7000 rpm chip in the MSD box........they were both installed at 215 lbs. of spring pressure on the seat...........
