Wow, I can't believe I'm asking such a seemingly stupid question, but....I can not find the timing arrow on my 66' 289. It's got to be on the driver's side because on the passenger side there is so much stuff blocking the view of the flywheel. I know many time by ear but I feel better sticking to factory specs, but the *&$%# arrow is not there! HELP QUICK want to do this tomorrow. Thanks much!!

On a true '66 timing chain cover, it'll just be a little nub sticking out, with what looks like a screwdriver blade (flat head) on the end. Sometime between then and '69 (don't know exactly when) they switched the covers, and they started using a bolt on timing mark with an arrow that is flat and actually protrudes over the balancer.

You may have the later chain cover without the bolt on pointer (my '66 is like that). I recently acquired the correct '66 cover and will put it on when the engine gets transplanted to my son's car in a couple weeks.

I would still "Road Time" the car. So many things come into
play with timing. I don't own a timing light! Never did.
My brother had one he used on his chevy, I think he still has it.
The damper could be off, I don't trust any of the old ford
dampers.

I just use my timing light to see how much total advance I'm getting and when I have it fully in. The initial is always set by ear.

Unless the dampner is new/rebuilt, there's a good chance the marks are off. And besides, timing specs are for totally stock engines, and even then they're the engineer's best "average". Start adding things like cams, tuned intakes and carbs, under-drive pullies, high output coils, and such, and all those factory specs go flyin' out the window!

Is there a simple instruction to "road timing"? I can never remember which way to retard and advance. My stang tends to run hot at times and I want to make sure the timing is not the cause. Thanks

Clock wise is adv. Take the car out and drive up a hill in drive, or
3 or 4 gear with a stick. You would want it to just not ping. Turn it
till it pings and set it back a little. Take a 1/2" wrench with you and
take your time. Some times I leave the wrench in the car and do it
over a few days of driving just to have some fun with the car, and
get used to the feel of the car. The type of fuel you use will make
a difference.

I believe that direction to adv or retard timing on a 6 cyl is in the opposite direction of a V8...
