Thanks guys for responding. I haven’t removed the distributor yet. I don’t have anyone to help me crank the engine unfortunately, but the rotor is pointing to the number one spark plug wire on the distributor cap, also I checked with a straw and the piston seams to be in the highest position when sticking the straw in the the number one spark plug hole. I Think it would be best to clean the balancer better and get a better picture. I guess I was hoping someone would recognize the orientation right off the bat. Thanks again for your help.
Just my opinion based on what I've learned from my own experience with timing, but I wouldn't waste my money on a Pertronix distributor. My local auto parts store has dropped that line because of too many issues with them. Not to say there have not been improvements since, but I think I would lean toward a reman Motorcraft or Cardone Select new Ford (style) dizzy with a Pertronix Ignitor II module and matching coil. DO NOT be tempted to go with an Ignitor III in a Ford. Unless Pertronix have redesigned the mechanical "bearing" between the two plates, you will have timing problems. I have posted on my experience many times on this. In my case Pertronix took it back and replaced the III with a II and coil and after learning how to rebuild and recurve the distributor to run 16* of initial mechanical timing, I couldn't be happier. I think the problem with most timing on 351C's is they were set retarded at 6* for emissions reasons, when in fact they need much more initial. HO engines were set at 16*.Thanks, I counted the ten hash marks as well and was fairly confident, but not certain I was at TDC. Still going to clean it up a bit more. I will definitely invest in a remote starter, great advice. Found one at summit racing for $12. There is about 3/8” - 1/2” of rotational play turning my rotor, so I’m thinking the gears my be worn, plus I can’t start the engine anymore. So I’m trying to get things perfect. Upgrading to a pertronix electronic distributor.
Andy, not saying the guy you got it from is full of sh*t, but just looking at your picture, it has a lot of crap on it for a relatively 'new' motor, unless there was an oil leak on the front seal or somewhere close by. It just looks off to me as well with the amount of paint crud on the balancer. If by chance you ever have the starter off, the block casting code and date code is just above that location. That will tell you at least what original date of that block was. Post a pic and someone will ID it for you. The head date codes are between the valves and easily seen, however, the head casting ID are under the intake ports and needs the intake off to see them with a mirror. A real PITA!That is a ton of information to absorb and I can’t tell you guys how much I appreciate the help. It is not the original motor and very well may be a 1972 motor. The previous owner said the heads were from a 1972 and it has square top pistons for a bit more compression. The car ran excellent when I bought it with plenty of power. I drove it 150 miles to get it home and the performance slowly declined to the point now where it won’t start. Started dieseling real bad and I had to shut the car off in drive or it would never stop. It started knocking bad on acceleration like the timing was way off. I took it to a mechanic and he gave me a list of things to upgrade including the distributor and coil. He wanted to pull the heads off and investigate burnt valves, but I didn’t want to throw that kind of money at it yet. The owner said the engine only has 17,000 miles since it was rebuilt. I’m replacing things that I feel comfortable with and that was recommended to me by the mechanic.

I'm not sure I see the same thing. I also believe the hash marks are 2deg increments. On the right hand side of the image, I see another 10 deg mark (had to zoom in to see) but I interpret this position to be 10 degs below TDC... Looks to me like the marker is directly over the 10 BTDC mark. This would be consistent with 2deg increments on the smallest hash marks.can clearly see in the image you're at TDC, I can count ten hash marks to the mark that reads 10 ATC
Ok WE tend to think that many work on cars 365 days a year!! It how you do a car a year or so! (Have always said "an hour a day no more NO LESS" ! Merry Christmas - I will take tomorrow off (kind of getting stuff ready for January Swap meet) ! LOLGreat advice all around, especially not to not cut any corners. I tend to get in a hurry. I won’t be working on it till after the new year, but I’m so pleased with this group and how helpful you all are. Looking forward to hearing mine idle again! Merry Christmas you guys.
