Turn the bypass regulator spring pressure up so it has the same amount of oil pressure as you shift it at(IE 70 lbs at 7000 RPM, 80lbs at 8000 RPM) or max RPM in high gear
I don't think I'm brave enough to run that little amount of rod bearing to crankshaft clearances even with aluminum rods cold I like and use the old rule of .0010 for each one inch of rod journal diameter
In other words I would shoot for a minimum of .0024 for stock Mopar rod journal size of 2.375 and .0022 on BB Chevy rod journals. I have and like to use .0030 + oil clearances on my race motors with steel rods on either journal size with no problems at all, .0035+ on the mains AKA aside, when it comes to high RPM drag race motor looser on the bearing clearances is far better than a tiny bit to tight

That video looks just looks it was taken here in the U.S.
it must be very hard to duplicate that look over there
Does Italy still have high import duties on American made cars and car parts?
I was shock at what the Aussie and Fins have to pay for are cars and parts
