I've got the EOS in the engine, and actually was going to check Courtesy Chevrolet and see if they had any more, I heard it was discontinued. I ordered some break in racing oil through Isky that's supposed to be high on zinc though for when I run out of EOS. Expensive though, like $6 a quart. Thanks guys. Looks like it won't be started this weekend though. It's pouring outside and I managed to break the carbon piece inside the distributor cap when installing the engine. Guess that's what you get for not having someone help you when putting the engine and tranny in.
