Speedway Motors 9108835 Details

Speedway Motors has all the parts you need to rebuild your Flathead Ford V8, including these high-quality main bearings and aluminum bi-metal rod bearings. Precision-built to the high standards demanded by today's rodders and restorers, these silicon bi-metal bearings main bearings and insert style rod bearings come in .010" undersize.

Crankshaft Main Bearings:

Improves Crankshaft Finish: Silicon particles reduce/eliminate microscopic ferrite peaks on improperly ground/polished nodular cast iron crankshafts.
Wear Resistance: During engine operation, silicon particles round off crank journal high spots, reducing friction and related wear.
Improved oil clearance: Because of reduced wear, silicon bearings make it possible to maintain OE clearances over the life of the engine, which reduces operating noise, vibration, and excess oil flow.
Tolerance Control: All shells matched to ± .0001" vs. the competitions' ± .00025"
Temperature Threshold: Silicon bimetal material melts/flakes at 662° F vs. tri-metal at 365° F.
Corrosion Resistance: Defends against corrosion caused by unleaded fuels and moisture.
Environmentally Friendly: All KING silicon bimetal engine bearings are "Lead-Free".
O.E. preferred material: Most O.E. engines today use and enjoy the benefits of silicon bimetal bearings.

Insert Rod Bearings:

Tolerance Control: ± .0001" vs. the competitions' ± .00025"
Superior Embedability: Material is much thicker than Babbitt overlays (.012" vs. .0008"). This provides greater macro-particle (> .0004" diameter) embedability. Macro particles are most responsible for scratching crank journals & tearing/weakening babbitt overlays.
Temperature Threshold: Bi-metal withstands 662° F (350° C) compared to tri-metal 365° F (185° C). Affords greater protection against localized overheating due to misalignment, detonation, overloading, loss of coolant, etc.
Conformability: Minimum depth of .012" enables greater adjustment to bore or journal misalignment without causing bearing failure or journal damage.

Overall Assessment

Customers consistently praise the product for its excellent fit and practicality, especially when used in the Ford 8ba engine. The bearings show remarkable precision as they fit perfectly, with spot-on clearances. Users indicate that the assembly process is streamlined which suggests the product's high usability. The bearings haven't been tried in operation yet, but early indications suggest they will deliver superior performance compared to alternatives. The tendency of customers willing to repurchase underscores their satisfaction.
