as far as oiling is concerned, I forgot about the "modification" I am going to plug the original inlet hole in the block, thread the hole where the little spigot goes into the oil nozzles, this will now become the inlet to the engine/outlet of the oil pump. thread the appropriate holes on the other side of the block and go through the FULL FLOW OIL FILTER then back into the block/main oil gallery. of course you will have to tee off for rocker arm lube, and fabricate the line from the oil pump to the block. personally I am going to run the line for the rockers outside the block, and use a bulkhead fitting through the valve cover, with some form of valve inline to cut down on oil flow. It will be a pain to get to the rockers to adust valves, but I work on large european equipment I'm getting used to goofy things like that. But you can go through the block as original if you like, I just don't like. If you have questions please ask, I can take pictures, and post them. I plan to make a whole procedure and post for any one interested. Once you get to this point of modification, there will be a fair amount of custom fabrication, and you will have to use common sense. OH AND ONE MORE THING...you will need a 54 oil pickup for that pump
