Milodon 11050 4-Bolt Main Caps Small Block Chevy 265-327

The Milodon 11050 main bearing cap kit provides a cost-effective solution for strengthening small journal small block Chevy engines (265-327 cubic inch). This three-piece center main cap set converts factory 2-bolt blocks to a high-performance 4-bolt configuration while also adding measurable strength to existing 4-bolt blocks.

Key Features:

• CNC-machined from high-strength ductile iron with optimal balance of strength and flexibility
• Splayed side bolts angle through block side walls instead of the weak main web area for superior load distribution
• Engineered to prevent "cap walk" by loading caps against register steps
• Complete kit includes all necessary bolts, washers, and drill bushing for installation
• Requires only 0.030" material removal for initial installation, allowing full cleanup on damaged or misaligned blocks
• Can be installed with basic hand drill and tap—no special equipment required
• Standard align bore completes installation on blocks with square main registers

This main cap kit effectively transfers increased shock loads to the crankshaft and bearings, making it ideal for high-performance street and racing applications. The angled bolt design provides superior clamping force compared to conventional straight-bolt configurations, helping prevent bearing damage and horsepower loss from cap movement.
