The engine had been sitting in a friends barn for years. He bought it for a spare but never needed it. It's missing the Rockers and side cover plate. Would I be able to use those parts from my 1940 engine that was in my truck? His oil pan was bad from sitting on the barn floor so I was hopping to swap mine over too the 46 also.
I've taken the engine down to the block and checked mains and Rod bearings. They are all between .0015 and .002 using plastigage. I've honed the cylinders and they look good and measure standard. I've pulled the cam and it looks good also. I don't believe it has many miles on it. My question, is there any tricks, special procedures or things I need to look for as I put this engine back together? I've worked on the Ford 4 bangers but this is my first Chevy Rebuild.
Thanks

Unless it is scrubbed with a stiff-bristle brush and HOT (virtually boiling) water and lots of strong detergent, then rinsed repeatedly with HOT water, there will be enough honing grit left in the cylinders to wear the rings out in a matter of a few hundred miles. I wore out a set of rings on a 2500-mile trip from California to Tennessee after an in the frame rebuild, and I had cleaned the cylinders with lacquer thinner and terrycloth toweling until no dirt showed at all on the rags. Still not clean enough!

I wipe the honing oil out, wipe the walls down naphtha or what ever is handy. Slobber oil on the rings and pistons so they slide through the ring compressor like butter and button it up.
I also use STP for assembly lube on everything that turns, slides or moves except the rings. Crank it with the plugs out until the oil pressure is up and start it up.
