Re: [FWDLK] 331 hemi timing questions



I'm not sure I would assume the marks are at the ten degree mark, he might have made the mark at the proper timing position. The lower mark seems to be the advance mark since the light shows the centrifugal advance or vacuum advance moving the timing down, try setting the timing on the lower mark and see how that works out. Can you see the original marks on the damper? One way to check to see if the TDC mark is correct is to pull the valve cover over number one cylinder and turn the engine by hand until the exhaust valve is closing and the intake valve is opening and rock the engine back and forth until it is in the middle of the opening and closing, look at the damper to see the location of the marks or make a mark because that is top dead center, although it is not on the firing stroke, if you check your rotor it should be 180 degrees from number one. Check your timing with the vacuum advance hose off and plugged, a golf tee works great. I hope this is clear to you, if not email me and I'll try to clarify.

Subject: [FWDLK] 331 hemi timing questions


I just installed the new pretronix ignitor on my 55 new yorker with the 331 hemi. I adjusted the timing but have a question that I can not find the answer too.

I adjusted the timing as per the service book at 6 Deg BTDC and on the harmonic balancer there is a line painted on it from the rebuilder about two years ago and a dot on each side I am guessing is 10 deg before and after .

My question is when I shine the timing light to time the car the timing is between the line and the lower dot on the balancer{ as close to 6 as I can get} is this location before or after TDC ? as the car runs and I just test drove it 45 miles { went for a ice cream run } and the only think I found is when I I went to start the car it was very slow to even turn over at first. I have found this happens if I do not change the battery every three years and the new battery I ordered came in a little small and I told them I need the larger size to fit properly.

Should I readjust the timing to read above the line when I look down with the timing light ? and I also noticed when i was adjusting it today that when I gave the car a little gas the timing went past the lower dot and returned to about 6 deg when I let off as I know this what should happen

I have not tried any other test so If any one has advise let me know. thanks again.
