Looking for 151M STD or King MB5849HP 455 main bearings
Hey guys,
I have a 455 build in process and can't seem to find and standard Federal Mogul 151M or King MB5849HP 3/4 groove main bearings. Stupid supply chain issues... If someone had a set available, that would be most wonderful. Thanks, Brent |

Never realized until recently but undersized bearings can be shaved to fit. (Not a perfect world...)

Thanks for the reply guys. I will discuss these options with my machinist. The 151M and MB5849HP bearings are well suited to use with a cast steel crank so I might be stuck waiting.

I found 8 sets of the Sealed Power 151M bearings for anyone that's looking. Well, 9 sets before placing my order. Check local availability, Joliet IL store specifically. Hopefully this information is helpful.

The PY Online Forums is the largest online gathering of Pontiac enthusiasts anywhere in the world. Founded in 1991, it was also the first online forum for people to gather and talk about their Pontiacs. Since then, it has become the mecca of Pontiac technical data and knowledge that no other place can surpass.
