Alright boys I'm lost, I've got a vibration from just over idle all the way to I assume redline (don't have the gumption to find out) I've ruled out the driveline and pump. Damper is balanced with weight 180 off TDC, flywheel has weight, removed alt. Belt, even ground extra material off mounting feet to ensure no contact with the floor. It runs great, no misfire, solid compression with less than 10% difference across the board, new plug wires installed yesterday. Engine came out of a running boat with no vibration. What am I missing??
Engine is a .060 over 454 externally balanced 2 bolt crank.
