BREAKIN IN MOTOR?

[woodward bird]

Guys i should have my fresh 390 ready to fire this week (was on vaca last week)and i had a few questions these questions are for antone but Joe vandatta you seem to be the t bird doctor from what i have seen in the short time i have been here so i hope i can get your opinion on this. Here go's

1. for breakin in what would you suggest for a oil i know not synthitic but any perticuliar wt or brand?

2. To pre oil can i just gut an old distb. and spin the shaft with a drill to build pressure and for how long?

3.once started should i vary the RPM or hold it steady at a certian RPM and for how long?

4. should i change oil very soon after initiale start up? And how long should i "baby" the gas till it will be ready to see what it will do?

I have heard alot of opinion on these questions and repect you guys advise so thank you for any ideas

Woody,
Any of the name brand oils are good, I would start with a 10-30 wt.
Pre oiling is a good idea but if you oiled all the moving parts on assembly not really necessary. On these engines you can fill the oil filter upon installing so you should pick up pressure in a few seconds.
What is very important is to let the engine idle untill you show good oil pressure--if not shut it down immediately.
Once oil pressure is established just take it easy for the first few hundred miles and I would change it at around 500.
Good luck,
Joe

PS-- Keep an eye on that temperature gauge, after overhauling my 390 the thermo stuck closed -- not good!!

Woodward you bet joe has given you GOOD advice but just for the sake of thoroughness and" free insurance "on a MAJOR investment I would pump up oil press. with a drill b4 I cranked it up.I might have spun a bearing on a 390 anyway I had re-done-but i fired it up w/o priming-don't cost aything to pump up oil pressure first.bj ;)
