Fits 1965-73 289/302. Sold each.
Ford 289-302 Main Support is designed to directly tie into the main caps. Our design doesn't need bushings or spacers and doesn't require the main caps to be machined to mount it. The end result is more support, easy to install and will clear up to a 3.40" stroke. This support is 1/2" thick and is laser cut out of steel with CNC machined mounting holes, includes all necessary bolts and washers.
FYI: In an effort to reduce costs and save weight, auto manufacturers started using weaker engine block castings as early as the 1970's. While these blocks hold up just fine when putting out 220 horsepower, they cannot go racing. Our Main Support helps to "beef up" your lower end by reinforcing the alignment of the main caps. The webbing on these blocks has much to be desired and a main support replaces the missing metal that the auto makers stole for extra catalytic converters.
