i just replaced the timing set - i used the line up the dots with strait edge to center lines - being a van with the front cover off i think i had a pretty good view - back together but radiator and cover off - starts right up - however i put a timing light on and timing is quite advanced - did i think to check before to see if it was that way ? no ( big duh) - doing some checking as best as i know - have vac line to dist plugged - have a vac gauge on the only other fitting on carb i find (holley 1920)- that is the one to the choke pod? - at indicated app 8 btdc about 650 rpm and 18 for the vac - at close to tdc vac and rpm drop quite a bit - quite a bit advanced and the vac goes up to 19 and rpm up maybe 670 - if i rotate the harmonic balancer so marks line up tdc the dist points to #1 terminal - does this sound ok or could i still be off a tooth on the timing set - want to make sure before reinstalling the rest of doghouse etc - thank you from the inexperienced - oo3

All you describe in terms of idle RPM and vacuum reading sounds like the cam timing is correct to me.

Too many people who were born on third base actually believe they've hit a triple.

I am right at 18 inches at 650 rpm at 16 degrees initial. So that sounds good to me!
