Well done! Welcome to the crate club! Me thinks you are going to like it!
What are your plans for breakin? What kind of oil did you use for it's birth? What kind of coolant did you use? Pics of the old motor's top with no intake?
Can't tell ya how to breakin, you probably already know what your gonna do, but I can tell you how I did mine.
I ran regular mineral oil at birth. Changed it every 1000kms(621miles?) for the first 5000kms(3100miles?). Then switched over to full synthetic. I've been changing it every 5000kms since. I also switched over from orange dexcool to regular green anti-freeze. The top of my motor with no intake had so much crude and corrosion in the water passages that I think one or two of the smaller holes were blocked. How was yours?
Oh and I didn't go Wide Open Throttle at all until after 5,000kms, and even then not too much until after 10,000kms(6200miles). And I tried to vary my Hwy speeds so I wasn't running constant speeds for too long until after 5,000kms.
Cool! Have fun!
