360 main bearings question

I have a 360 block that was built in 1970 and I use #1266 full grove bearings. I spin mine to 7,700 rpm through the traps and It runs in the low 10's like 10.10 at 131mph. Never had a problem. Full grove is the way to go keeps oil on the rod bearings all the time. Be sure to run a high volume oil pump with a big oil pan 7+ quart and you will be fine.
