Hello All,
Well you finally have me straightened out on my HEI conversion, now I only have one question remaining and it is concerning the timing marks, On my marks, it looks like on the counter clockwise most part of the marks there is an "A" then a bunch of hash marks, then on the furtherst clockwise, there appears to be a "B or 8" Cannot really make it out and then one in the middle of the 2 that I would assume is TDC, which mark should I try to align the timing light to to get 8 to 10 degrees BTDC?
Thanks so much everyone for you help previously and now
Rick
