Help with timing! I'm Electrically Challenged

I'm great with mechanical and suck with electrical. Planning ahead for when I start my 327 for the first time to break in the cam. I'm confused about setting initial timing. I'm reading it should be set at 12 - 14 degrees initial. When I start the car and take it to 2000 or 2500 rpm, do I start it and then disconnect the vacuum advance and set at that number at the break in rpm? Do I start it with the vacuum disconnected? Does it matter? Is there a way to get it close by setting the distributor to a certain position before starting it? Does anyone know of a step by step tutorial that explains how to do this? Sorry for all the questions but I don't want to screw it up. Thanks

Get a friend to help you when fireing this engine and breaking it in.
Get a friend to hold the throttle and rev the engine to 3500+rpm while you adjust the timing using a timing light. to ensure it is at max mechanical advance. Set the timing at 32-36deg BTDC while it is reving up.
rev it up, it may not fully max out until past 3500+ rpm.

Ignition timing is always set/adjusted with vacuum advance disconnected.

Then reconnect the vacuum advance and run the engine at 2500+++ rpm for 1/2 hour. (vary the rpm up and down, above 2500rpm) Be sure the rad is full of water/coolant and the engine gets plenty of air flow thru the rad to keep it cool.

avoid idling the engine for the break in. If it overheats or has other issues, noisey valve train etc shut it off and fix it. Then re start quickly and continue the run in.
Do not allow the engine to overheat.

I like this stuff in the oil for engine run in.

www.molyslip.com Moly slip E oil suplement.

Its a lot easer on you and your neighbors to do with the full exhaust system installed.

when installing the distributor turn the crank so it is 15deg BTDC on the compression stroke and drop the distributor in so the rotor points to the #1 spark plug wire on the cap. This gets you close so it will fire quickly.

Aftermarket timing pointers are never accurate. correct yours using a piston stop to find true TDC on the balancer.

36deg BTDC is 1/10th around the circumference of the balancer.

Just to add a little emphasis to F-bird 88s suggestions
- Definitely disconnect and plug the vacuum advance line.
- If you line the timing pointer up to about 12-14 degrees BTDC on the balancer and then drop the distributor in so that it is pointing to number one on the cap, you have a good approximation of the timing advance you need. It should at least be close enough to get it to run for the break-in.

When I broke in my last cam the engine started to run hot before I got through the suggested 30 minute break in. I just shut it down and restarted to complete the break-in after it cooled, and it worked fine.

Quickest way I know is to put #1 on TDC compression stroke. Remove #1 plug and ground it. Connect the plug wire.
Bring your timing mark on the balancer to 14 or 16* BTDC, turn on the ignition switch, with the dist loose turn it until you see the plug fire. Snug up the dist cus it's close enough to run perfectly until the cam is broken in.
