Well I finally got the 350 running today and it is making a weird noise while idling. I can't figure out if the valves are incorrectly lashed or if it is a rod knock. The car while idling sounds a bit like a diesel engine. It makes that kind of cak-a-lak sounds but as I increase the RPMs the sounds seem to go away. When I was building the engine I pumped up the lifters with oil the best I could and then installed everything the proper way and did the valve lashing. Could the lifters have pumped up to full and now the lashing needs to be redone? Also when I was building the bottom end I used Clevite 77 bearings. The crank was not cut so I replaced the old bearings with standard size 350 bearings. There was one problem with some of main bearings though. When inserted into the block they stuck up a bit, like they weren't flush with the engine. This didn't let the main cap sit completely down so I had to shave a little bit off the bearings which tightened up my oil clearances to where they were within spec. Has anyone every expirenced this problem before?
