I believe it's a reman, Have 10 hours on break in and all is well, Temps staying at 150 and 40psi on oil pressure through out the 10 hour break in varying rpm's not exceeding 4000rpm...

Do they not call for an oil change ? They may have done the initial break in at the shop, so don't sweat it if you haven't.
