New 289 Ford Hi-Po main caps .Here is a set of new 289 Hi-Po main caps that have just been re-produced. They are exact replicas that are cast and machined here in the USA from the original Ford blueprints.

A set consist of caps numbered 1- 4. We did not bother to make the rear main cap because it is almost identical to the non Hi-Po cap and very difficult to machine with the seal surface.

These caps are cast from the highest quality Nodular iron and machined for ease of fitting to any 289 block.

The I.D. of the main bearing bore is .020 undersize and the side registers are .010 over size on each side for proper adjustment before line boring and fitting to a block for the first time, The caps have the proper style number on them with the arrow facing forward just like the originals. A beautiful part that will enable you to make your std. 289 block into a 289 Hi-Po block. Original 289 Hi-Po caps can sell for as much 1500.00 and if you need a set don’t hesitate .
