🔧 Part Overview: OHIO QUALITY 16101-M STD Main Bearing Set

This is a New Old Stock (NOS) main bearing set from The Ohio Piston & Pin Co., part number 16101-M STD. The “STD” suffix indicates standard size, meaning it’s designed for crankshafts that haven’t been machined undersize. The packaging style and branding suggest mid-century production, likely from the 1960s–1970s.


🛠️ Application & Fitment

Based on cross-referenced listings and similar part numbers (e.g., MS-16101P), this bearing set is compatible with:

  • Chevrolet small-block V8 engines, including:

    • 283, 305, 327, 350, and 400 CID

    • Used in 1955–1980 GM passenger cars and light trucks

  • Fits standard housing bore and standard crankshaft journal diameter

This part is equivalent to aftermarket references like MS-16101P STD from Federal Mogul, Sealed Power, and Clevite. These bearings are essential for supporting the crankshaft within the engine block and maintaining proper oil clearance.
