Any one interested in the oiling mods I did?

My take on the oiling system crossover tube for the small block

You know what works better at slowing fluid velocity? Increased galley diameter. This would make tubing the lifter galley a bad idea if fluid velocity was definitely a concern, and if it was then bushing the lifters makes more sense..

Since they decided that reducing the diameter was the way to go, I question how serious of a concern oil velocity actually is.

Also, the text mentions increased mains clearances which will definitely have more of an effect on the distribution since the increased volume demand will drop the local pressures upstream and then make it tougher to get oil to the drivers side galley.

But if fluid velocity is reaching the upper end of laminar, then placing the crossover where they did makes sense - so if you're going to put it somewhere, the location is well determined.
