Maybe I can paraphrase Ted S here. The best thing to do is to make a drive
adapter and pull the distributor and prime the lub system with a hand drill.
Run the drill until you get pressure and see oil coming out of the valve
rockers. Then sit down for a few minutes. Have lunch. Or a beer. Then do it
again. Then wait for another 15 minutes. Then do it again.
If you have a new camshaft the next thing is to seat the cam and lifters.
Reinstall the distributor and set the timing. Prime the carbs and start the
engine and run it at 2000 - 2500 RPM for 20 minutes. Shut it down and change
the
oil and filter.
After that it is time to seat the rings. One school of thought is short
bursts of heavy throttle (whilst driving) will develop pressure that will force
the rings into the cylinder walls and seat them more quickly. Another school
of
thought is 1000 miles of gentle driving. Sounds like a life style choice.
Good luck
See you tonight.
Dave
