LSK lobes and higher RPMS.... I've searched quite a bit and there really isnt much on this topic. Anyone running an LSK lobe cam spin above 7K? I'm looking into trying this lobe on a 24X 24X cam but want to spin 7200ish and not sure of the spring stability.
BTW the valve train would be the new extreme springs, Morel lifters, Manton pushrods, and Harland Sharp rockers.

I'd say it probablly wouldn't work due to the fact that the 240x ish lobes are in the .650"ish lift range. The springs are good for .660", which is very close for optimal valvetrain standards. You have good parts in the valvetrain, but with the Harlan rockers and the LSK lobes, your very likley to have stability issues. You may want to look into a PSI 1225 spring (.700" lift), or titanium valves. I would also reccomend ditching the harlan rockers and going with the stockers, rebuilt by harlan.

Thanks for the input! Do you have any other info on these springs? I havent totally made up my mind about the HS rockers but I do have them in case I want to go that route.

Endurance Spring: Dual (O.D.: 1.445") (I.D. Outer: 1.060") (I.D. Middle: N/A) (I.D. Inner: .775") (Seat Pressure: 140lbs.@1.950") (Open Pressure: 435lbs.@1.200") (Rate Lb./In.: 393) (Retainer Step: .070") (Max Lift: .750") (Coil Bind: 1.100")
Are these the springs you were referring to?
