360 LA installing Promaxx Aluminum heads
Shower thoughts saved me 2~3 weeks for a custom set. I tried on those Comp 7821-16 pushrods last night (7.396 Overall length)with the adjusters all at 0 thread showing and thought they were too long. For some reason I was thinking the rockers should all remain neutral and free as I tightened the shaft. Apparently "thinking" was my mistake. I've compiled a notepad document I've been referencing with measurements and such as I go. I was looking over the numbers just before I hit the shower... something was bugging me. Then mid shower it hit... some of the rockers are going to be opening valves as you tighten dummy! Why I thought otherwise last night I dunno.
Sooo.. off to the garage I went. Put the Comps back in with adjusters on the rockers set to 0 threads showing & torqued the shaft down 25ft lbs. Set the first 2 rockers to 1/2 turn past zero lash. This is the result. About 1/4 of a thread showing. Realistically a better fit than the set I was going to have made as I was shooting the middle. And to think I was going to return these today. :eek:
