| dale, did you have good oil pressure? if so one of my suggestions/ or questions would be to check for a wrist pin knock. Im no pro butit could be possible. also if you have the pan off the bottom end check the thrust on the crank. belive it or not, I just got done replaceing a .010 under crank that broke in half in my 390 with only 50 - 60 eazy engine break in (no pun intended) miles. It knocked like crazy after it broke but I still had great oil pressure at idle, and above. I dont Know about you but I havent herd of this happening to many people at all, but it happened to me first hand. I think during the machineing process the crank got mis handeled or droped or some thing and formed a hire line fracture in it I wish you luck on your engine maybe this info will help. Lets hope its some thing simple. |
