10/35 is conservative timing more so the 10 especially with no vacuum advance. Make a mark on your dampener at 2&7/32" clockwise from the TDC slit to verify you are at 35 total. If good there I'd get the TDC tool & install it in the #1 plug hole & verify that the TDC slit is correct but I imagine it will be as dampener slippage is rare. Sure sounds like too much timing though. EDIT I reread the posts & it WAS running OK at one point with this timing correct? I was thinking the cam could be machined wrong but that is rare & I always want to k.i.s.s. but same deal it ran OK prior with this cam/timing. Something ain't adding up
