shudder
I just did new heads (stock) on my 86 351. The carb is freshly rebuilt, new pugs, wires, cap, rotor, and the list goes on..... I don't want to offend anyone but all traces of emissions are now gone. The only things that are left for vacuum are the essentials, vac advance, shift modulator on the tranny, brake booster, etc. The truck runs really good, but you can feel an ever so slight shudder to it if you are leaning on it, parked at an idle. It isn't vacuum or carb adjustment, those issues have been addressed. We have not put a timing light on it yet simply because we haven't had to. Can anyone think of something I might not be?
