Thanks for the replies. Still not sure what to do about that half-covered cam bearing... will wait to hear more.
As for the cam plate and plugs, I didn't have a hollow bolt with my original cam plate. Nor did the plugs have holes in them to allow any oiling to the timing chain.
In the How-To books I have (2 of them) for Small block mopars, they say an alternative to a hollow bolt system is drilling a tiny hole in the left plug to allow a small bit of oil to squirt out and help keep the chain cool.
Just curious if anyone has actually done this or if i should go find me a hollow bolt!
