New stroker. Vid and ? I'm loving this new 408 in my truck...
http://video.google.com/videoplay?do...08147324226694
got a question though. Motor has about 400 miles on it. 4 oil changes with Rotella T 15w40. Making more and more power everytime.
Idle pressure has gone from around 55 warm to 45-50 warm
Figured the bearings are breaking in and the tolerances are loosening up... anyway figured it was normal. Pressure still gets up to 75-80 @ WOT.
Am I correct about the bearings loosening up?

Bearings don't break in. The crank rides on a layer of oil and should never touch the bearings. If you notice that your oil pressure is lower even after you changed the oil then there might be signs of a problem. Check your oil the next time you change it and look for metal shavings.

I think you'll be fine. You are changing the filter with these oil changes right? Run an K&N filter see if its any different. I've seen the best results with these in both my LT1 and LS1s for oil pressure and maintaining oil pressure (6.000 miles synthetic changes)
