540 build

I like the 'ol McCandless mod of enlarging the feed passages to the mains to 9/32", and reworking the pickup hole to accept a 1/2" pickup tube.
Of course, it all depends on the desired usage and power level IMO...If he's looking to go much over 600hp in a 540, or it's gonna see a lot of strip time it's probably best to get away from the stock oiling system. Otherwise the simple mods I listed are fine and plenty of guys don't even do that and don't have problems.
