I have a Chevy SB 350 and need to adjust the valves after break-in. I am relatively new to working on engines, so I need some assurrance.
I have hydraulic lifters and factory rocker arms. Prior to starting the recently overhauled engine for the first time, I adjusted the valves using a somewhat arbitrary method; tighten until there is no rocker arm play. As you can see, I am leary using the engine until I do it right. It runs well, but I want be be sure the valves operate at their optimum.
Based on some internet research, I found the following procedure: warm up the engine; pull the valve covers; set to TDC; adjust the appropriate valves (i have a chart) by backing off the nut until you can spin the push rod by hand, tighten up the nut until it won't spin (zero lash), then tighten up the nut 1/2 turn more; then rotate the engine crankshaft one revolution and do the other valves.
Any better ideas?
