Hey all,
I know there has been lots of discussion on this but everyone's application is different so here I am.
I have a 1963 GMC with a 327 with a slightly souped up cam (not sure what, as it was like that when I bought it)
I am running a edlebrock 600 and my tranny is the sm420
I have vacuum advance and a vacuum gauge to test with but I can't seem to get it right. I have used my timing light and put it at tdc ( I assume the middle line is tdc) but it still will not run at optimum.
There are no vacuum leaks. I am just not sure how to adjust the dist., then the fuel screws on carb and then the idle screw or in which order for that matter.
Any advice from you oldtimers (not necessarily in age) would be awesome.
Signed up and coming oldtimer to be:)
Thanks
