Put 57 miles on the new motor today in 38* weather.
Man, it runs sweet! I've only run it up to 3500 so it's hard to get a real good idea on the power, but it feels great! I am really shocked at how quiet it is. i expected these cams and the roller rockers to be noisier. You can hear the valvetrain a bit at an idle, but it's not objectionable at all. And as soon as you pull away with it, it pretty much goes silent. I am also surprised at how streetable it stayed. So far, it doesn't seem to have any bad manners at all. The cold idle is working perfectly, but once it's good and hot, it is idling about 100 rpm too low. That could have been why it needed some throttle to start in the video. it hasn't needed any help starting for me yet, though.
While it was out on the two-lane and moving, the oil temp hovered between 190* and 200*. At the end of a 15 minute, or so, period in town and going stoplight to stoplight it was at 220*. That is similar to what occurred with the stock motor (20-25* increase in town). I will be keeping a close eye on the oil temps as the break-in continues and as air temps warm up this spring.
It has about 90 miles on it, now, 75 of that on the street. The second 100 miles will see 4,000 - 4,500 rpm. Looking forward to seeing how the cams pull on the other side of 4 grand!
