George PAdmin.

Thanks for sharing the update Monty. So how do you plan to proceed?

By the way, I do have part numbers for Crane spring cups designed for 1.5" OD springs. #99465 has 0.570" ID, #99455 has 0.637" ID.

I played with the lift numbers & coil bind numbers last night and came to the conclusion that with an installed height of 1.82" either spring should be good for up to 0.600" lift. Its cool that PAC's reply validates that. I believe Crane's rating of 0.660" max lift is based on an installed height of 1.88. At 1.82" installed height the Crane spring will have 114 pounds seated force, the PAC spring will have 120 pounds seated force.

I will be needing to update the valve train section of sticky #3 after I figure out how to make room for additional text.
