318 Timing Chain Question.

I'm leaning toward leaving on TDC #1. then be careful to get it right with Dots on 12 and 12.
Use a straight edge to verify. It would have to be a tooth off to get it wrong.
I will have an issue that I'm doing it from high above looking down, and cannot get a front view. I guess I could use my iPhone and take a Picture to confirm/compare.
Opinions?
Well, what most people do is time it dot to dot for the ease if installation, then turn the crank ONE revolution and you're on #1 TDC. But, if you didn't pull the distributor, you can time it dot to dot and you'll be fine. It's all relative to exactly WHAT you're doing and you've not disclosed that yet.
