Please help me with timing
The original settings for my 1968 428CJ according to chiltons should be 6 degrees BTC. The harmonic balancer has a TDC with a - numbers on one side and + numbers on the other. I am assuming that +6 is 6 degrees BTDC, however the car has run on, not bad but just slightly and the car runs very rich. I have tried to adjust to -6 BTDC but the car will not run at all. What am I missing here? Whats up with the - & +. The engine was built by a professional race engine place so I doubt the cam or crank gear is off a tooth. The engine does have all high performance parts, how much does this affect the orginal timing? It has 160 miles on it so far. Would like to take it on an extended run this weekend, but I don't trust it yet. I would appreciate any help.
Thanks very much.
