Main Caps, Milodon, 350, 4 Bolt-Angled Caps for factory 2 bolt block

These aftermarket main caps will strengthen not only factory 2 bolt blocks, but also 4-bolt blocks. Unlike the factory caps, these have more cross sectional strength. Milodon main caps are CNC machined from high strength ductile material, which has the proper balance of strength and rigidity to allow the transfer of increased shock loads to the crank and bearings. In this case, more is not better when it comes to hardness. Available for straight and angled bolt applications to suit your needs. All bolts and washers, as well as drill bushing are included where necessary to aid installation. For additional strength, Milodon head studs are recommended. Only .030" of material removal is required upon initial installation, which will allow 100% cleanup on a damaged or crooked block.
