• Here is an Ebay auction for a set of used Hipo main bearing caps by Ebay member "mustangmanbob" with a Buy-It-Now of $635.00 or make offer:

    This is a set of 5 main bearing crankshaft bearing retaining caps.

    They are original Ford.

    They have been cleaned and are in excellent shape.

    They are straight sided, not the tapered sided caps that are found on a standard 289.

    This fits all HiPo 289 engines 1963 1964 1965 1966 1967 and would have been on Mustang Fairlane and Shelby Cars.

    A reproduction set of 4 sells for $740 on the west coast.

    They will be shipped either FedEx or UPS, so I will need a physical address.

  • These caps being advertised as Hipo are actually Mexican caps. The problem as Mexican caps is that, even as Mexican caps, they are incomplete. The rear cap is for a standard 289. I have already let the seller know about all of this.

    Ford 289 HiPo 5 main caps, K code, Shelby GT350

    Original set of 289 HiPo main bearing caps including the correct rear main that many sets are missing

    #1 cap has some rust pits

    #2 cap has some minor rust pits

    They have been sandblasted to show clear view.

    These have to be align bored to the block they are installed on.

    The #2 cap minor pits should be pretty well removed when align bored

    The #1 cap pits well be removed to some degree but some will probably remain.

    There will still be plenty of unblemished area to add the correct support for the bearing

    If in doubt ask your machine shop.

    any questions ask
