this is a ford 390 with non adjustable rockers.Hydraulic cam. Plug wires checked out. Both valves are closed at #1 cylinder. piston pushed out air on stroke and rotor pointing at #1 terminal inside cap.Im starting to freak a little.When i installed cam i lined up cam and crank gear marks as described. New gears and chain. could it have skipped? maybe i need to advance timing more. I hate to keep spinning motor blindly.
