interesting.....i guess you could be 180* out....since the distributor is driven off the cam if they put the cam in at BTC instead of TDC alignment would be 180* out of synch. i guess some one could have screwed up a rebuild and then walked away from it in frustration.

if it was 180* out wouldnt the compression tests be normal.....at some point in the cycle wouldn't it find two closed valves? or would the two closed valves always happen at BTC?
