Re: Cam Change
To be clear, the idle is not real bad, just have gotten use to modern cars where you don't even feel the engine idle. Never stalls, just a little bumpy.
I have already readjusted all the valves 1/4 turn from 0 lash per the documents. Yesterday I pulled all the plugs check them and reset the gap to a specified .040. They actually looked pretty good with a few thousand mile now. Light brown on on side of the porcelain insulator. Adjusted the timing to 12 BTDC and adjusted the idle and idle mixture a bit. Also made sure I had no vacuum leaks at the carb base and hoses. Very little change. I have about 15 inches at idle in park which is about 800 rpm. In drive 625 rpm and 10-11 inches of vacuum. If you have a manual trans or maybe a looser torque converter it might be a bit bitter. Still looking at all options.
