Is it an aftermarket bolt-on tab or is it welded to the front cover? >First, my timing tab is located 1.25" from the balancer, which introduces >a lot of parallax when you try to adjust the timing. As André suggested, perhaps the tab's for an 8" damper. >Shouldn't the degrees on the timing tab measure the degrees around the >balancer? Is my tab off by a factor of two, or are my calculations off? Remember that you're timing the ignition and that the distributor turns half as fast as the crankshaft. Could this explain the doubling/halving you're seeing? One of the easier but often overlooked tasks is the verification of TDC. Either buy or make a piston stop and verify that the timing mark on the damper is at the 0 mark on the tab when the piston's at TDC. This is a good idea especially when an aftermarket damper and/or timing tab has been installed.
