no idea where the timing is.

Thanks for all the help, it is runnging again. Put a timing light on it and set it at 16 BTDC (w/vacuum adv disconnected and line plugged. Idle at ~750. All of that was done with it in Park though...No bog when I get on it. haven't stayed in WOT too long, tie rods are shot so its a bit scary right now.

While working on it, I noticed that the previous owner had the vacuum advance hooked up to the small vacuum port above the air fuel mixture rather than on the bigger port located at the base of the carb (front corner on the passenger side). Which one is correct? didn't seem like there was much vacuum comming out of the smaller one...so I switched it. Assuming I should plug the smaller one above the air/mixture screw.

Seems like I can get more out of it, Can I trouble you guys to talk me through fine tuning it a little more? All the back and forth working on it today raises a few additional questions in my mind.

1) what order should be followed when tuning? Timing, idle, air/fuel, idle again
2) adjusting the idle speed should be done with the vac adv reconnected right?
3) what kinda vacuum would be normal for this engine (described below) I messed with the mixture screws a little but vacuum stayed right around 10.
4) I thought with this cam, the idle should be a little lopey, but its not (so maybe it still aint exactly right)

Engine was done several years ago by the previous owner. 69 340 40over; X heads,headers, holley 4bl vac secondaries (CFM 650 I'm guessing) comp cam high energy Cam 268H. I don't know squat but the specs don't look to much more aggressive than factory.

as always, thx in advance and appreciate the assist
