rebuilt engine break in oil

[pjq]

Great information guys, thanks.
I just got back from the engine shop and he does carry Joe Gibbs and Royal Purple so I now have a supplier of Joe Gibbs.
Because there is not a conventional 40 wt Joe Gibb oil, he suggested for the second stage of break in to use a conventional vavoline or castrol 5w40 with a zinc additive from a GM dealership. So it sounds like he's on the same wave length as Jake and Charles.

What about changing transmission oil.
Other than Porsche what is the next recommended brand? I was told by a Porsche dealer to use a synthetic 75W90. Anything wrong with Joe Gibbs or Royal Purple?

Buy the Porsche 75W90 synthetic gear lube from Sunset Porsche. Cost about $25/quart. You need 3.

I've bought a fair bit of parts and supplies from Sunset for this project, they've been very good.
BUT they won't ship liquids, they're not the only ones. Even the Porsche dealer here in eastern canada won't ship liquids, its a liability issue I've been told. So unless I drive and pick it up I can't use Porsche transmission oil. The local porsche dealer (4hrs) brings it in by the barrel, no gallons or litres, so I can't buy it there.
