Newbei 67 Plymouth belvedere 318 2bb dist vac port is timed or full.

Yep C, just like you mention, the 1405 manual states "if emission controlled"
Good point!
Ok so now that Im starting to (at least trying to) learn more on carbs n timing, if you use the full time port for distributor, do you set timing with that as well?

BTW C, your the least disagreeable person. Thank you for the info/advice
