The CANTON Ford 351W Main Cap Support (SKU CAN21-062) is a critical reinforcement component specifically designed for high-performance Ford 351W engine builders. This support structure addresses a known weak point in stock 351W architecture—main cap deflection under high horsepower loads. It is ideal for builders focused on street performance, mild boost applications, or competitive racing.
Engineered by CANTON, a manufacturer renowned for its expertise in engine strengthening solutions, this main cap support works by cross-bracing the engine block's lower end to eliminate flex between main bearing caps. The robust high-strength steel construction and precision engineering effectively distribute load across multiple mounting points, converting the block into a more rigid structure. This design helps maintain bearing preload consistency and prevents crankshaft walk under high-load conditions.
This Ford 351W main cap support is particularly beneficial for builders planning significant modifications, such as displacement increases, cam upgrades, or forced induction systems. Its heavy-duty construction is tailored for engines producing power beyond factory specifications, ensuring reliability and performance in demanding applications.
