This material choice does not establish a horsepower limit; fastener selection must also account for the application and required preload.\u003c\/p\u003e\u003ch3\u003eSelection Guidance\u003c\/h3\u003e\u003cp\u003eThe specified cap arrangement, block design and windage-tray requirements determine which kit is appropriate. A similar displacement or engine-family name does not establish that different main fastener kits are interchangeable.\u003c\/p\u003e\u003cp\u003eConfirm the block, main-cap arrangement and any girdle or windage tray before ordering.
