Looking for a timing Authority... Re '39 Six

Posted by Packard Newbie On 2016/12/25 0:10:01

I have researched timing on the net and gotten conflicting and ambiguous info. My question is: if the engine is at TDC on the timing light and one is trying to achieve 6-7 degrees BTDC, do you advance or retard from TDC??

And am I correct in my thinking that retarding the timing will slow the engine down and advancing it will speed it up???

This may sound very neophyte but I can't get a straight answer via my Shop Manual, nor Googling the question online.

Thanks to any who are willing to read and respond. Merry Christmas to all the Packard folks out there!!
