I'm not familiar with that particular part number? But I think that is a babbit alcohol/fueler bearing.

If so I wouldn't use it - it is designed for large clearances and a thick oil cushion, babbit will wear faster - a friend ran some in his street motor years ago and within 2K miles his oil pressure was dropping.

I don't know if there are different grades of babbit material but I know he ran a set of fueler bearings in his.. he got such a good deal on them.

I just went thru this for a street hemi myself, I went with the 877P as it is a hyd cam motor.

1/2 groove, full narrow groove, 3/4 groove, wide groove they all have there merits.. I went with simple and proven
