I have a 327 with a mild camshaft. Problem being at idle (750 rpm) the timing reading is 40 degrees. The car runs good at this setting. When I adjust timing to 13 degrees it runs terrible. Timing cover has a spot welded pointer and the balancer is approx. 7 inches in dia. Any and all info. would be helpful.

Are you checking it with the vacuum line disconnected? Try it that way and see what you get.

yes vacuum line is disconnected while checking timing.

timing..

I don't thionk it is possible to get 40* advance at idle with vacuum disconnected....somethings sounds funny. Are sure the distributor is in correct...??? is the timing tab damaged....??? different damper..??? it doesn't make sense to me...

I agree...I am getting a "false" reading. The harmonic balancer probably not more than 50 hours on it. When no. 1 piston is at top dead center the timing mark on the balancer is also at tdc. I am puzzled.

Areyou sure your timing light is good and you are using #1 cylinder?

 

[Dogger]

I thought about the timing light...I will try a different one. Thanks for all the replies. Any other ideas or suggestions ?????

is the balancer degreed? or are you using a dial advance timing light? Do you have MSD? I've heard not to use a dial advance timing light with MSD. is the timing pointer spot welded to the timing cover like stock? and you say the mark on the balancer lines up with the 0 mark on the pointer @ TDC? did you verify true TDC when the motor was assembled?
