351W's NEED extra bearing clearance because of their huge 3" size. I would look for 0.003" and would be using 3/4 groove racing bearings. Unless you are using watery thin oil, I would look for between 0.0030" and 0.0035" on the mains. 0.0025" on the rods.

Install a high volume pump for insurance, and add a large BAFFLED oil pan that will provide a total capacity of around 8 quarts. Canton makes some nice units. Get one that is either DEEP and narrow, or has the 'roadrace' baffles. 'T' pans with wide bottoms and no baffles are NOT good when the oil gets sloshed around.

As for the accumulator... not a bad idea, but address the above first.

Good Luck!
