Did you put some assembly lube or motor oil back on the RM bearing befor re-installing it?
Vaseline in an oil pump is common. No problems there.
HOWEVER, for the little trouble that its worth, I would still yank the distributor to "prime" the system. Vaseline only lubricates the oil pump...you will still starve your bottom end for a few seconds, and to me, that's not worth the gamble.
You CAN just turn the motor over with the starter to prime the system, but again, I would just yank the distributor real quick and use a drill to prime the system. Remember, you have NO oil in the pump/pickup, unlike when you change your oil. Also, did you remove the oil filter? That is another part that could be a potential problem! I always fill the oil filter FULL of oil before install....especially a new filter! Its a verticle oil filter and easy to do.
