I'd be checking that the timing marks are still accurate on the harmonic. I've had a couple that have moved considerably and they tend to move in the retard direction. Also check the harmonic isn't loose on the shaft. These engines aren't overly sensitive to timing really. I had my stock 3.9 LC locked at 15deg (ie 15 deg static and no advance) for a couple of years before fixing the distributor. Barely noticed a difference after fixing it... My v.high comp stroker is much more sensitive to timing, but the lower comp stockies just don't really care that much (as long as you are in the ballpark, within reason). And that little cam still counts as basically "stock" in my book... If you need that sort of static timing then there's a problem somewhere.
