What does 'standard size' mean for these main bearings?

Standard size bearings are designed to fit a crankshaft that has not been machined undersize. If your crankshaft is still at its original factory dimensions, or has been reconditioned back to standard size, then these are the correct bearings for your engine.

What is the importance of oil clearance with main bearings?

Proper oil clearance is critical for engine longevity. It ensures a thin film of oil can circulate between the bearing and the crankshaft, reducing friction and heat. Too little clearance can lead to seizure, while too much can cause excessive wear and noise.

Are these bearings suitable for a stock engine rebuild?

Yes, while marketed as high-performance, these ACL bearings are well-built and manufactured to tight tolerances. They offer excellent reliability and support for both stock rebuilds and engines that will be used for performance driving.

This set fits a variety of classic Ford and related vehicles, including the Ford Cortina, Ford Pinto, Lotus Seven, Mercury Capri, Morgan 4/4, and TVR Vixen models from the late 60s through the mid-70s, with some Morgan models fitting into the early 80s.
