Factory 2 Bolt Compared to Milodon Cross Bolt
The new cross bolt design is now in stock.
Both R Block - 383 and RB - 440 caps.
426 Hemi, new Gen III Hemi and LS Chevy can all handle 800-900 hp with a stock bottom end. Why? Because of cross bolted main caps.

- Gear drives provide "new engine" power for entire life of the engine, no chain stretch. For steady timing — a gear drive is the strongest and the most accurate, period!
- Accurate and consistently precise timing will make your engine run better and harder.
- Professional "3 gear" setup is far different than the cheaper "4 gear floater" setup.
- Available for all Chevy, Mopar, Ford, Pontiac and AMC engines, since 1967
