Ok, with #1 at the top, and dist pointing to #6, when I turned the engine, the #1 intake valve started opening. So is it right, or is it 180 off?
Did you say the timing marks on the cam and crank are both at 12:00?
The cam mark should be at 6:00 and the crank gear mark at 12:00. they should be pointing at each other.
both at 12 is #1 firing.
If you put it at crank 12, cam 6 it's #6 firing.
Guess where the cam timing dot is when you rotate the crank 1 revolution?
Watch the #1 intake valve when you roll over the engine, when it starts to close, look for the timing mark/cover, it's on compression that time by.
Both marks pointing up and not pointing at each other you are at #6 tdc. The marks should be pointing at each other....Crank mark straight up @ 12:00 and the cam mark straight down @ 6:00 to be timed at #1.
Correct me if I'm wrong:
If the intake valve is just starting to open, then the exhaust valve just closed, which means the rotor should just be passing #6.
If this is correct, then I have it installed correctly.
I'm positive that the distributor is in the right way. When I had the timing cover off, I put it at TDC (cam and crank timing marks both at 12 O'clock) and lined up and marked the distributor then.
I was a bit startled when physhy said the marks were both straight up when he had the timing cover off and wondered if it was timed correctly. For #6 yes but not for #1. Mike
Exactly. I never even need to pull the valve cover. I just bump the starter till it tries to blow my finger off the number 1 hole with the plug out. then with a socket and breaker bar align damper and cover marks at tdc.Doesnt matter how cams phased. Then turn distributor till rotors pointing at number 1. Do you have points? if so make sure they are opening and closing.Just bump the engine until #1 intake closes up, that's #1 firing as the balancer mark comes to the cover timing mark. NO BS about cam crank dots or anything else.

good question.Do you have power to to the coil in crank?
