The result was a push Rod length of approximately 9.100"-9. Strong, vacuum die formed light weight rocker arms. I repeated this procedure on the #1 exhaust and the #1 intake until I observed the motion of the roller tip that satisfied me I then actuated the valve train through one cycle to observe the motion of the roller tip across the tip of the valve stemĥ. I then tightened the Adjustment Set Screw another 1/2 turn to "pre-load" the lifter (as if to make a cold adjustment)Ĥ. I proceeded to extend the APR until I removed all slack in the assembly (presumably this is an unloaded zero lash condition)ģ. I installed the Adjustable Push Rod (APR) on the the #1 exhaust with the #1 Cylinder 0 deg before TDC on the compression strokeĢ. I backed the Adjustment Set Screw as far back as I could until the cup on the end of it was flush with the body of the rockerġ. Ok so I didn't go the route of the lash caps but I did already have the adjustable push rod so here's what I did and maybe you guys can provide a sanity check here.Ġ. If any one has had this problem please let me know how you solved it I remember reading somewhere that the Yella Terra's use Buick V6 Push Rods What are the stock push rod lengths for the 250 CI L6 versus the 200 CI L6 I was very lucky in that the Block had never been rebuilt before and it only needed to be decked like 0.005" (I have the real number written down somewhere) to get it true again but I don't know if that is indicative of any pushrod short comings? My suspicion is that the pushrods in my kit might be the wrong length for my application. There is no threads for the lock not to engage with. I am trying to do a cold adjustment before I start the motor and then I will do another warm adjustment but I can't even do that yet because on the cold adjustment with the #1 cyl at TDC of the compression stroke I try to adjust the valves and the adjustment screw of the rocker on the #1 Exhaust has to be screwed all the way in such that it can't be locked. Has any one here had any trouble adjusting the rockers after installing them. I am using a Comp Cams custom grind in conjunction with the CI aluminum Head.
