Mikes reply:
In the beginning the Rocker stud nut was cracked and I replaced them with 7/16" screw- in studs , because I was bending the Factory Push rods. While there, we installed the Johnson Hydraulic Lifters, a new oil pump and HD Chrome moly Push Rods, had a new timing Gear and dual chain. I drove for about four years testing and tuning. "

Was just trying to clarify when the lifters were added since this statement doesnt say "when", just "in the beginning"

The Butler people had me find the round part of the Cam and the valve is closed and we could spin the push rod some, with some tension on it, then 3/4 turn to seat the push rod into the lifter. We marked each push rod so we could see it spin, while running. The stud kit came with a Bolt a washer and screw in stud. And when you ask me something, please let me tell the story my way, it is only fair.

Sounds like you adjusted the rockers then... when you tell a story, please include only pertinent details & timeframes, makes it much easier for others reading, thats why I had to ask to clarify the lifters and rocker adjustment.

I read that today's Motor Oil has no ZDDP, that is why I must add it to my old 1967 Pontiac.

You read wrong, ALL of todays oils have ZDDP in them, and at pretty good levels around 900-1000 ppm, which is adequate for factory stock cams & even some bigger mild cams. Modern oil also has other anti wear additives like moly that protect cams & internal parts, no factory cam need crazy high amounts of ZDDP and adding too much by pouring in an unknown amount additive is also not good for the engine.

you said:


"Not going back through all the pages, myself & others have lost track of most things posted in this thread. Thats great if you actually removed main/rod caps & properly measured for clearances, hope they were all within spec."

No not yet, but we did provide some limited info. as I have stated. If I ever take this Motor down that far, to get those type of measurements, it would be rebuilt as I come back out, for sure.

OK, then you didnt actually measure the bearing clearances, that can only be done by removing the caps & using plasti-gauge or the right measuring tool.

Sorry for trying to clarify some things that arent very clear or providing facts on some of the statements made, there is no argument on my part, just stating facts in an effort to help, but apparently myths & flawed opinions over rule facts.
