7M GTE ignition timing guide needed...

The car shouldn't even run if the CPS is 180? off. First off, when you installed the cam gears, which holes did you use for alignment with the dowels? You need to use the center ones, they're not all drilled for the same placement.

Also, if you use a dowel to locate TDC and find that it doesn't match the marks on the harmonic balancer you need to black out the original mark and make a new one at the real TDC.

There's a thread in the FAQ about setting timing and what the marks look like. Look it over, for some reason people try to set the CPS using the dowel as their marker which is way off. I suppose that if the CPS was rebuilt is could have been clocked wrong when re-assembled. If you take off the CPS' cover I believe the rotor should be clocked to the 1 o'clock position.
