about to put this 4.6 block all together later this week. Block, heads, crankshaft and all the bits were taking to the machine shop and cleaned up and gone through but we didn't replace the camshaft bearings. Camshaft is going to be replaced with the Crower 53229. The engine is out of a 2003 D2 with 100,000 miles on it. Only the front camshaft bearing shows any noticeable wear, but based on my online findings, this is common. I am wondering if the wear on the camshaft bearing seems appropriate or not
