Just put distributer and everything back in. What is the best way to set the timing?

Here's the way I set initial timing when I remove the distributor. (Before I remove it I have the rotor pointing at #1 plug wire terminal on the distributor cap and this gets it close to the proper timing mark on the flywheel, in your case 7oBTDC).Since I assume you just removed it,( and lost the timing) you'll have to find the compression stroke on #1 cylinder. You do this by removing th spark plug on #1 and have someone tap the starter while you hold your finger over the spark plug hole. The compression stroke is occuring when you feel your finger being pushed off the sparkkplug hole. Look at the flywheel timing marks and try to get to 7oBTDC. You can fine adjust it by using a wrench on the crankshaft bolt to move the flywheel to the correct position. Note where the #1 plug wire is in the distributor cap and insert the distributor into the block holding the rotor pointing to the approximmate position of the #1 spark plug terminal in the cap. Try to engage the teeth on the camshaft to allow you to end up with the rotor in that position. Tighten the hold down just enough to allow the distributor to rotate with some drag. Pull the # 1 plug out of the boot and put a bent piece of wire or a paper clip into the plug boot. Turn on the key switch, hold the #1 plug wire near a good ground and slowly rotate the distributor in either direction until the coil fires the plug wire. At that point you are statically timed. You may have to do it several times to get it right. When you do, tighten the distributor down, put the plug in, attach the plug wire and start it up. You should check it with a timing light at idle and adjust as necessary. Also increase the throttle and make sure that the timing advances to check that your centrifugal advance mechanism is working.
Hope this helps you.
