Product Description

Cobra Automotive’s reproduction 289 Hi-Po main caps are exact reproductions, cast and machined right here in the USA from the original Ford blueprints.  A set consists of caps numbered 1-4 with the proper style numbers and the arrow facing forward, just like the originals.  The rear main cap is not included because it is almost identical to the non Hi-Po cap and not cost effective to machine.  Our caps are cast from the highest quality nodular iron and will fit any 289 block.  Bearing bore is .020 undersize and the side registers are .010 oversize on each side for adjustment prior to line-boring.  These beautiful caps convert a standard 289 block to a Hi-Po block.  Set of four; requires final fitting and line boring.

  1. New HIPO Main Caps 5 Star Review

    Not cheap, but quality seldom is. The oversize enabled my machinist to accurately fit them to my block.
