Hello
I got a ragtop 68 bird with a  400 that sat for 15 years i had it running once or twice but now I cant get it to start. I replaced almost everything, plugs wires dist, coil, qjet,..., I was going to replace the points with an electronic unit but somehow it got fried and I went back to points. Putting the dist back in I brought up the number one to TDC on compression got spark and fuel but its not starting.
I finally pulled the timing cover and found the timing marks at 12 on the cam and 12 on the crank!
Doing a bit of searching here I found someone saying the timing should be at the number 6 plug not the number one.
any ideas or comments would be really helpful!
thanks
Steve

With the timing marks both at 12 o'clock you are at #1 TDC. If you now rotate the crankshaft 360 degrees the crank timing mark will be at 12 and the cam timing mark will be at 6 because the cam rotates at half the crank speed. This is #6 TDC. You could install the cam in either position and still be correct, (the same). Just make sure the distributor rotor is pointing at #1 plug wire when both timing marks are at 12 o'clock.

Dave thanks for the reply. Just to make this perfectly clear, once everything is back together all I have to do is bring the number six cylinder to TDC on the compression stroke and set my dist to 6 rather than one?
If this works I owe you a cold one!
Thanks

That would be correct.  Its not uncommon two get distributors 180 degrees out of phase.
