I have a mild built 390. When starting to adjust the valvetrain I brought #1 cylinder to TDC. The timing marks were aligned, but the piston was halfway down the cylinder. My original balancer was rough looking, so I thought that the outer ring must have spun on the hub. So I purchased a new balancer from Jegs and installed it last night. Brought it up to TDC and same problem. I removed the fuel pump, and can visually see the timing dot on the camshaft sprocket is pointing down when I visually bring #1 cylinder to the top of the cylinder. So that tells me that the cam and crank sprockets are alinged correctly. The part number of my original balancer is COAE-6316 B. Any suggestions will be greatly appreciated.
