Detailed Description

Size: STD / Series: H / Material: TM-77 / Journal Size: 2.750" (RB Engine) / Oversized Fillet Clearance Champher: YES / Oil Groove: Full .100" / THESE FIT 1974-79 RB (440) blocks only. WILL NOT FIT 1973 and earlier engines. Originally developed for Nascar racing, H series are made of TM-77 material, however they are not flash plated with the lead/tin apparently in an effort to help them seat better. They also have enlarged champhers to help them clear bigger crankshaft fillets. They also have a medium level of eccentricity. A good overall performance bearing.
