The SBC Main Caps (350-4bolt) by MILODON are a vital upgrade for builders of small-block Chevrolet engines who seek enhanced durability for high-performance applications. These main bearing caps are crucial for both street and competition engines, particularly where factory components may fail under increased loads and pressures.
Constructed from high-strength ductile iron, these caps offer superior clamping load distribution and reduced flex compared to OEM castings. The four-bolt design significantly improves crankshaft stability at high RPMs, which is essential for preventing catastrophic bearing failure in high-displacement and forced induction scenarios. Precision machining ensures optimal crush clearance and oil film consistency.
Ideal for performance, race, or turbo applications, these main caps are essential for any serious 350 engine rebuild. Proper installation requires honing alignment and the use of ARP or equivalent main studs to achieve the best results.
