? about pushrod length I'm putting in an ASA cam and already have Crane quick lift rockers. Check my math and see if I'm thinking right. Stock rockers+ASA= 7.425 Crane rockers+stock cam= 7.250. So wouldn't I need a PR .025 longer than the 7.250 to be back around stock geometry and lifter pre-load? I have a PR checker, but the rockers make it hard to use it so I figured math don't lie, why not calculate it out. I've found 7.300 PR's, would these work and if not where could I find 7.275's?

7.250, you have adjustable rockers now, you can make your preload whatever you want, but shoot for the 2 full turns that crane asks for. you won't have any issues. i know people who run asa cams with stock length pushrods, and they are fine. the crane rockers are very particular with there pushrod length, to achieve perfect geometry and preload.
