How is the engine driven/used?
How fast dies number 2 take to arrive at 80 pounds?
388, I presume is a .060 over bore on a 350 block. That begs the question what is the block?
Have you checked the cam for a wiped lobe, like at number 2?
Who's heads? If they were rebuilt, did the guides get refreshed?
What are the piston's and rings?
Do you know what finish was put on the cylinder walls?
