Vacuum Advance for 1965 327-375 HP w/Transistor Ignition
I have a 1965 L84 375 HP FI with transistorized ignition.
Have hard starting problems when hot and will try to replace distributor vacuum advance to see if this helps.
1. Where does one order these from?
2. What is the correct part number for my car?
I have tried part # 1116236 on e-bay and amazon.com and got nowhere.
I tried AC Delco and they list a part # D1316A but it does not appear if one can order directly from them and my searches do not turn anything up for that part number.
Very time consuming and frustrating I must say! I hoped some of the experts here might help.
I tried to search the forum but could not find anything applicable for my 327-375 HP with transistorized ignition.
Am a new member and may not be searching properly.

The VA can will not solve your problem. The VA has nothing to do with hard starts. You have other problems

If you're letting off the throttle as soon as the engine TRIES TO START, you're probably backing off a little too soon on the throttle. If the engine starts, hold the throttle down until it clears out and starts running right.
What I described is a common situation. I can't tell from you description if you have another problem but it won't be the vacuum advance.

The VAC has been discontinued but you might find some old stock at GM Parts Direct in NC or RockAuto online.

Vacuum Advance Unit
Frank,
The vacuum advance unit you need is a Standard VC177 or a NAPA Echlin VC1810. This is the can that starts to pull in at 3-5 inches of vacuum and is all in at 6-8 inches of vacuum. Any auto parts store should be able to get one for you if they are still available. Any auto parts store should be able to get that AC-Delco unit also. The unit should be stamped B-28. But, as most others have said---that is NOT the cause of the hard starting, but it is always good to have a working vacuum advance for idle stability and cruising economy. By the way, TI and regular ignition take the same can.

Assuming your engine has a 30-30 cam & your idle vacuum is about 10/11 inches HG you need a Standard Auto product p/n VC 177 stamped B28. Other P/Ns are
ACDelco 1312C
Borg W. V329
Niehoff Dr 305
