Best oil for break in

[AmadeusCharger500]

I am about to start up a rebuilt 440. It has a engle street cam. Everything is fresh. I would like some advice on what oil to use for break in (type and viscosity) and then what type to use for the first few hundred miles.
I have read that truck oil has some of the best additives to prevent flat tappet cam failure, is this true?

Shell Rotella-T 15/40 diesel oil with a bottle of GM EOS (engine oil supplement) which is available at any GM dealership.

Hey Ron,

Now did you read that article in HOTrod about cam failure, or is this just part of that library in your head?
Yes, yes I know the answer allready.

Yes I sure am going to Carlisle, all 3 days too. I have a Hotel booked for friday and sat.

So whats up, are you going to swing by? Its just a short what, 11 or 12 hour ride?
(Man that would be great.)

Naw....been using that brew for the last couple of years.  We broke in Dave's (the Arrow) Engle cam last summer using that mix and he's running the Rotella as his everyday lube. So far so good. Change the oil & filter right after break-in and again at 500 miles....then regular intervals after that and you're good to go. 

Ya, i'll be down for the show.....thursday to sunday. We need to hook up. I wanna see your car !

I did the same as above. So far so good and the oil pressure is great.
