I'd run on the large side of the factory specs for a race engine. SteveW

Steve, do you prefer to use higher clearances and a high volume oil pump? Or just a regular oil pump?

Although engine block oiling design, intended end use for the engine, oil pump, and oil viscosity all play a part in determining the ideal bearing clearances, a rule of thumb for a performance engine is 0.001" of bearing clearance for each 1.000" of crankshaft journal diameter.------------------ Ted E. Fe's are plenty fast, but "Y"'s are fun when they run in the nines.
