Woodsman, The motor i am running is a RMRE 565/HR which i believe is what you have. My buddy bought it from them at the beginning of the year. The motor smoked like a friegt train but it was fast. I bought it at the end of the year from him. First thing i did was call them to see why it was smoking. They put me through to Johnny, he pulled the build sheet and told me it was the material the second ring was made out of, did not make alot of since to me. The motor had 150 runs on it so we decided to pull the intake and change the lifters and springs. When we got the intake off the back side of the intake valves that were closed were covered with about 3oz. of oil each. As it turned out it turned out the bolts that hold the rocker stamds did not seal! We fixed the problem and it turned out that the second ring was a backcut ring which didnt make any since. At the end of that year the cheap GM windage tray had broke off into little pieces, clogged and sucked the in, and went into the oil pump locking it up and breaking the oil pump shaft. As you know it lost oil pressure and was finished. When i had it freshened we found the second ring thing! Also the main bearings were cut down in width. Some of these things i dont agree with just to get a few HP. But in thier behalf every time we have taled to them they have not had an attitude i just didnt take it back there to be freshend.
