    Go with a AOD and enough gear to make the boss happy.

    The cam specs are similar to the hipo 289, but the had a higher rocker arm ratio.

    My 69 Boss had a service block, too.

    Don't forget the BOSS 302 had HP 289 rods(5.15") with a special shorter piston Regular 302 were 5.09"..........
    so enters the "long-rod theory" debate!:D

    The 289 Hipo and B2 rods were slightly different- the 289s had a rectangular bolt head with a straight cut through the rod, while the B2 had a "football" head bolt, with a simi-circular cut through the rod
     
  5. In all reality with the advancements in cam technology a roller cam would be the way to go. No worries of the cam going flat, oil compatibility, and the list goes on. Depending which way you go, a stroker even with aftermarket crank rods and pistons. Upgraded heads with the aforementioned roller cam. $$$$$$$$$$$$$

    I bought a couple rods in 70 or 71 to replace ones with spun bearings in a 65 K code from a Fairlane. The parts book showed the replacement rod as a C9ZZ-B which was a Boss 302 rod. The details stuck in my head because, typical of Ford, the rods cost 75 damn dollars apiece 50 years ago.

    In 1971, a Boss 302 short block was $350.00, head castings were 48 bucks. The titanium intakes and sodium filled exhaust valves were $175.00. A Hilborn injector was $450.00. I know, because my Brother built one to run in a sand dragster. A couple years later the one I bought needed 4 rods, and new block. The bare block was $200. and the rods were $15.11 each.

    Looks like that dealer screwed you big time. Above add has them 8 for $88.60 in 1971.

    May have been like me when I was younger, either go to NAPA or the Chevrolet dealer for parts.

    If NAPA didn’t have it, I had to spend 20 bucks at Chevy for a set of 8 plugs.
    Same damned R44TS plugs too. Lol

    I like Ferds but yeah, you could build a heckuva hot rod motor with the cash that Boss 302 will bring. On the subject of stealerships, I don't remember the numbers but I slid my OT high school car backwards into a curb (long story) and bent the axle in the Dana 60 rear end. The young and dumb version of me ended up paying waaaaaay too much for that axle. When I had the bearing pressed onto it, the dude at the parts store asked if it was off a truck. Nope. A 4-sp R/T Ch@rg3r.

    ""you could build a heckuva hot rod motor with the cash that Boss 302 will bring""

    Tried selling the one I have, no takers. Got to be strong enough for over 500 hp?

    When I bought my OT Super Cobra Jet I contacted SEMO M****ng. They were great on the phone and knew what was what. All they specialize in is '69 and '70 M****ngs and even though they are a thousand miles from you, they can probably direct a customer of theirs who is dying to find a Boss 302 right to you. When I bought my hot rod, they had 3 customers with this car on their wish list and a price they would pay sight unseen.
