dist. mechanical advance ajustment?
340 timing was a bit different than a 273/318 in the linked thread.
So here's 68 Plymouth. Dodge was sometime spec'd a couple degrees different.
This is the high compression - a late lower comp 340 prob had a slightly different curve but either way this gives you a ballpark that should be close.
Interesting. Comparing it now to the 273 HiPo - they are very similar. :)
