8k rpm ...

Thanks Rumble
I guess I forgot the most important part, The oil pump was a HV HP melling that was fitted to the cap and all oil passages cleaned up with long drill bits, opened up about .010 - .015" not much but made sure they were straight through clean, no burrs, rounded all corners that needed it. It had a Milidon pump cover with a 1/2" pick up out the bottom straight down to the bottom of a custom pan with 2 trap doors and baffles, held 7 qts with 1" cut off the dip stick tube so the oil level was 1" lower in the pan. That's about it, no crossover tube, no blocked or restricted passages, I ran this motor on the street and the track for probably 15,000 miles in 30 years had it apart at least 6 times about every 5 years and it looked like new every time. I had the motor in my AAR when I sold it and it still had the same bearings that I put in it in 1977. Here is a picture of the motor I took it out of the AAR to put in new freeze plugs they rusted out over all the years.

If you had that pan (which is now about impossible to find and I have two of them...one with a 1 inch static pick up and the other with the swinging pick up) then you had the 1 inch pick up tube. That's a massive help right there. A 1/2 inch pick up can't supply that pump much past 7000 RPM without serious issues.

So that was a big deal.
