[QUOTE="ROKRIG, post: 1243376, member: 18487"] I'm referencing both a Chiltons and Chevrolet OEM factory manual specifically for this motor. I'm kinda thinking I'll adjust the #6 exhaust rocker arm on the compression stroke per the instructions and even if it's loose on the second revolution when hand-cranking, I'll put everything back together and fire it up. Maybe the oil pressure will take out the slack? I've confirmed the compression stroke by removing the #1 spark plug and hand cranking the engine until my trusty helper (wife) felt air coming out of the spark plug hole. I then turned the crank until the mark on the pulley lined up with the zero degree mark on the timing scale. Sound correct? In addition, since for some reason I have 2 grooves on the crank pulley, I confirmed which groove corresponded with TDC by inserting a dowel into the #1 spark plug hole, measuring the amount the dowel was inserted when each of the grooves was aligned with the 0 degree mark on the timing scale. Sound good? [/QUOTE]
