Removing Cam bearing
So as im prepping (cleaning and detailing) the block for the new heads and cam ive noticed that bearing number 4 (front to back) is shot! I have already ordered new bearings along with the installation tool but im starting to wonder if its even possible to replace all 5 bearings without pulling out the block??? I thought I read in some forum that you can but im not 100% sure

Yeah, its a tight area, but you can drop the pan and get view of it all. but like i said, close area to work in.

In order to pull the cam bearings, you have to pull the plug out of the back of the cam bore. Engine needs to come out.

You can prolly do the rest without pulling the engine, so long as you have the clearance to get the tool in from the front.......

Correct on the sizes.

You should be able to get the #4 out and a new one in without pulling the block. You may very well need to remove the radiator though, and possibly even remove the AC condenser. You must pull the block to remove all the bearings from the block as the front one requires removing the Welch plug in the back to pound it out from the back. The lip that holds it in place makes it impossible to drive out from the front.
When you get that tool, it should have an extension with it. You can use that extension to get to the #4 bearing if the longer part won't fit. Put a deep well socket over the threaded rod and a socket extension in the deep well socket and bang on that to get the proper length to reach the #4 bearing. Stuff a bunch of rags in the block to catch the bearing when it comes out do you don't have to fish out the old bearing from the oil pan, or drop the pan to remove it. Be darn sure to line up the oiling hole in the new bearing with the oil passage in the block. I believe it's at the bottom of the bearing's mating surface (6 o'clock position), but BE SURE. Might even want to snake a wire down that oil passage just to make sure it isn't blocked by the shavings of the old cam bearing you are relpacing. I did a thread with a cam swap over at bionicdodge.com with an explanation of what I did with the cam tool, I'll try to find it and post it here.
