How to tell if it's hydraulic or mechanical cam?
Back on the old project, 1969 block, 1.94 heads, 383 motor. Compression was all over the place 140 to 185 pounds. Intake roller rockers are 1.5's, exhaust are 1.65 (not sure why though). Anyway, assuming it was a roller hydraulic cam as the previous owner said, we reset all the valves today. Taking each cylinder to TDC one at a time, we took both sides to zero lash and gave it 1/4 turn more. It didn't fire and so I checked 1 and 3 real quick = no compression now. Maybe solid lift after all?
I suppose that means I just screwed up, but without taking everything apart, how can I tell what the lash should be set at? It's a Comp Cam setup, but we have no specs at all. Suggestions?
I hate being stupid, but it didn't run anyway so I really haven't lost that much ground...lol.
