Brand new main bearing nicked. Usable?

famous bob said

The center 3 mains are the weakest, due to not being incorporated in the front and rear block walls , and the bottom shells do receive the most ponding.
If u think there is no stress on # 3 thrust bearing in a hemi or big block, why do they go south occasionally in hi h.p. , hooked up drag cars?
It was enough of a problem that the Chrysler drag seminars had some teaching on them back in the day . Most teams back then changed bearings on the prostock type cars regularly.
I lost a thrust bearing in a hemi s/s car once and learned of the problem from Tom Hoover.
Of course a lot if u younger guys probly don't even know who he was.
He was called the god father of the hemi.
Things have come a long way since then tho in engine and bearing design , I guess-----------

Take a look that the firing order and you will see that the center main takes 4 consecutive hits in one revolution from ,3,4,5,6 cylinders, that is the reason Ford changed the firing order in 302, 351 and in the end changed the later year 302 to the same as the 351 windsor. As far as incorperating the center mains into the block ? Look again ! What would you call the webbing between the bolts and the pan rail ? Most all V8 engines suffered from the same problems this post is about. That is why Chevy changed from the small block to the LS order, why cam grinders offer a 4-7 swap cam for many engine, why Ford has a different order on nearly all of their engines. There are cams that go beyond the 4-7 swap with 2 more cylinders but that simply moves the load from the center main to the 2 and 4 main. Better that I suppose since you now have load sent to all 5 mains, the rear, not much to do about that one with a heavy fluid filed convertor or heavy flywheel, and the front, a belt with tension on it all the time and a chain to run the cam or cams with tensioners on them as with the Tritons and a couple of others.
