BB Chevy engines have relatively light pistons, given the low deck height and short r/s ratio and long strokes. Certainly lighter then a BB Mopar.

Physics don't change, but our understanding of them certainly does. Just look at what happened in the 1940's when those wacky physicists came to understand how to split the atom and put a good chunk of the Japanese real estate market under violent reconfiguration. I don't believe for a minute no one has learned anything new since 1917. More pointedly, oil flow/control in an engine involves far more than simple physics.

I'm assembling an R3/W7 engine of about 393 cubes (3.79 stroke) that will spin to about 7500RPM. I want it to make 3000HP+ but in the interest of cost, space, and reliability I am aiming for 700HP lol.

• At that engine speed you don’t need to modify the oil feed system. You can use full groove mains, a HV pump and get the oil there all the time, as much as you can.
• A quality pan, with a rear sump and a big diameter pickup tube helps bigly. A crank scraper is money well spent. The Ishahira-Johnson Teflon scraper for the drivers side and their down scraper is what I use. Worth every penny.
  
• The stiff block is a much a big deal as anything. If you are using 340 mains and a 30 grade oil (maybe a 40 at that power level) you can squeeze the main clearance down to .0021-.0022ish. That helps.
  
• Very cool build. Updates will be appreciated.
