Q & A

What's in the Box

Stock Ford small blocks don't have four bolt main caps so we recommend using our steel main girdle to increase the strength of the bottom end. Includes 5140 steel studs, nuts and spacers.

Note:   1979-1995 Ford 302 engine main caps are different than the pre 1978 289/302 engines. The 1979 and newer 302 engines may require extra clearance around the main caps.
