Re: 72 K10 350 skips after warmup
Been there done that. Over time the push rod cup on the rocker wears out sometimes. Mine was on an exhaust valve so it was backfiring thru the carb pretty good. Glad I don’t use Holley junk so no blown power valves. I just replaced the rocker arm and have driven it for close to 2 years since this happened.
