Good news! Pushrod length checked out perfectly! The Howards pieces are beautiful and well made.
Bad news! The rocker arm stud is wrong yet again. The previous ones didn’t have enough shank on them, and the trunnions were sitting on the threads- no bueno. So the ones I got today are perfect, except now the threads themselves are too long for the set screw in the adjuster to be functional, it’s hanging way out of the nut. Too bad, because the trunnion is fully on the shank and the nut runs out of threads just as 1 turn past zero lash is achieved (Howards specifications, not mine).
After paring through the Summit catalog and the terrible descriptions of the dimensions, I finally got sick of it and waited on hold with ARP for 45 minutes to talk to a representative. We think we have it worked out. So those are on order, and I also ordered a set of ARP’s own polylocks since they are a bit taller and allegedly the set screws are shorter per the rep. But we’ll see. The polylocks will arrive tomorrow, but if they’re not the fix then I’ll be dead in the water until the studs show up next week.
