Any one interested in the oiling mods I did?

Well what you are doing when you use the cross tube and block the oil to the #1 main from the right galley is you are not feeding a lifter galley off a main bearing. This directs more oil to the main as it is now the end of the line. In other words none of the oil that is reaching that bearing has to go feed anything else except the rod bearing.

As for that mod doing something for the #4 main I don't see it, but I'll be the first to admit I don't know it all.

Oh and as for restricting oil to the #5 cam bearing, I'm looking into that. Haven't found a way to accomplish that easily yet.

And for the tube, I've seen it done a couple different ways including AN fittings and braided hose. You'll have to experiment with that.
