Big Block Chevy
Milodon's Main Caps are designed to strengthen factory 2 and 4 bolt blocks and at the same time stop 'cap walk'. These main caps offer more cross sectional strength do to the side angled bolts, delivering more side pull of the side walls of the block and not on the flimsy main web area. The side bolts heavily load the cap against the register step, therefore reducing the chance of bearing damage and horsepower loss. The main caps are CNC machined from high strength ductile material, which has proper balancer of strength and rigidity. All necessary bolts, washers and drill bushings are included in the kit.

- More cross sectional strength
- Reduces bearing damage and horsepower loss
- CNC machined from high strength ductile material
- Includes bolts, washers and drill bushings
Note: For installation, only .030" of material removal is required, which will allow 100% cleanup on a damaged or crooked block. The drill bushing used to drill and tap the side bolt holes is included in the kit. The side bolts can be installed by anyone with a hand drill and a tap. If the block has square main registers, the block needs only a standard align bore to finish the job. Milling the mains is only necessary if the main registers are not square.
WARNING: Motor vehicles contain fuel, oils and fluids, battery posts, terminals and related accessories which contain lead and lead compounds and other chemicals known to the State of California to cause cancer, birth defects and other reproductive harm. These chemicals are found in vehicles, vehicle parts and accessories, both new and as replacements. When being serviced, these vehicles generate used oil, waste fluids, grease, fumes and particulates, all known to the State of California to cause cancer, birth defects, and reproductive harm.
WARNING: Some dust created by power sanding, sawing, grinding, drilling, and other construction activities contains chemicals known to the State of California to cause cancer and birth defects or other reproductive harm. Some examples of these chemicals are: lead from lead-based paints, crystalline silica from bricks and cement and other masonry products, and arsenic and chromium from chemically treated lumber. Your risk from exposure to these chemicals varies, depending on how often you do this type of work. To reduce your exposure, work in a well-ventilated area and with approved safety equipment, such as dust masks that are specially designed to filter out microscopic particles.
