8k rpm ...

I don't believe you, but it really doesn't matter if I do. lol but I have to wonder what was the oil pressure at 9000rpm
I don’t lie.
Hamburger oil pan, that held 8 quarts. Hv Melling pump, Ed told me to Swiss cheese the windage tray.
It ran a decade with only a few times coming out to inspect and file fit new rings, and fresh bearings. Same rods, and crank, forged junk speed pro pistons.
Always had 63-70 pounds of oil pressure above a couple thousand rpm. fully grooved bearings with .003 clearance.
Do I recommend spinning a 340 that high?No. But don’t act like it’s not achievable, cause that’s not true.
When using the nitrous I shifted around 6,500 cause when it my brain to hand time was around 7,500
But on the motor I spun it a little harder, as it always ran better, closer to 8,000
This engine is a little bigger and will be shifted at 7,800
