What main bearings for a high performance engine?

maca said
Hey guys I'm rebuilding my 360 stroked to 408 turbo magnum. It has around 800hp at the crank. I will be spinning it to around 6500 RPM.
Just wondering what main bearings people are running in the bigger horsepower engines. I have read that half groove bearings are better to take the extra hp loads but full groove bearings seem to be more commonly available.
Anyone had any experience running both.
Clevite 1266hg and
ms1051p clevite
Are the two I've been looking at

For that power level you should use the "H" series clevite bearings.
The "H" is for high performance and these series of bearings have features for high performance such as increased bearing clearance,
Increased bearing crush, and they are a harder bearing. Imho
That motor should have a lot of other block oiling mods as well imho.
