    Holding up real good. My biggest worries are tearing a driveline out so I just try to drive it like an old man. But I still end up passing everything. I just don’t understand it

    You’re right. I do like it. But I really do try to light foot it and keep my boost down

    Im in Anc. I did the inframe myself and was very meticulous about the build. I went by the book, double and triple checked my work. I did set the cam gear backlash and checked it 3 times. I ran the overhead and re checked it after break in. Only a couple minor adjustments. I had 2 different very experienced hd mechanics look at it as well. They had no answer. It did quiet down a bit once the oil got circulated. I can still hear it but it doesnt sound much different than the 2 other 6nzs i compared it to. Maybe its in my head. It seems to run very well. I have a trip to Fairbanks in the coming days so i will see how it does.
