I have a 250 6 cylinder in my 66 c20 that came out of a late 60s vintage vehicle of unknown origin. The valve lash currently varies between cylinders, but I am not sure if the motor has hydraulic or solid lifters. Is there an easy way to tell with minimal work? I plan on adjusting the valves, but need to know which type they are. I heard on the late 50s 235 6 cylinders that the cars had hydraulic and the trucks had solid lifters. Any input is welcome. Thanks in advance!
