28* initial timing for a 318? How can that be?

I think thats enough snips for discussion while still falling under 'fair use'.
Curious if there are any observations about piston dwell time and intake valve closing points. In your own words is fine. Just a couple of other factors that can come into play with spark lead.

I think one could theorize the crap out of how timing might be affected by different variables.

Not sure how I would design the testing to actually prove it. You would need to control all the other variables so you can see the results of how just that single variable does or does not affect the timing.

As a thought experiment, how would you set up the test to determine the effect that piston dwell time has on the engines timing requirements? What variables do you see as a challenge to control?
