  1. Nice! My dad had a bronze/black 69 with the 426 and auto transmission. It had all the options but was short lived as he totaled it before it was 2 years old.

  2. My 5L v8 in my 2019 Ford truck makes 395 HP stock. Ed Jones

    1. And, in 50 years, NOBODY is going to want to restore it.

  3. Anon,
    HP was measured differently than today, those many years ago. Measured at flywheel or differential? Some HP ratings were minimized by the factory to reduce car insurance rates. The Ford Turbo V6 truck motor also has gobs of HP. Electronic timing, constant fuel/air ratio changes, etc. give a big boost to newer motors. I would love your truck (I drive an old Ford PU) but also love this Canary Yellow Roadrunner!

    1. "...to reduce car insurance rates"...and maybe try to get a favourable class at the NHRA track.
      Bought a '71 Mustang out of state in '77. Gave the VIN to my insurance agent. "Is it a v8?" "I think it is". Looks in a little booklet, and pronounces "20% surcharge, for excessive HP". Factory rated at 370hp, NHRA factored it at 475hp. U-tube dyno runs of that engine package show a bit over 500hp stock.
      Mach 1, 429 Super Cobra Jet, Ram Air hood, 4.11 Detroit Locker, with the very rare Fairbanks modified C6 auto transmission.

  4. My old MGB could lose one on a curvy road. Pissed 'em off.

  6. Looking at that pristine engine compartment, that beauty probably doesn't ever get fired up, even to drive up on a trailer to go to a show. Good for some I guess.

  7. 1963 Buick Riviera 401 CI Nailhead. 525 ft/lbs of torque. Old school motors make lots of torque that sort of make HP irrelevant. I test that principle daily in Medford Oregon. Takes 700+ HP of new school to match. It's not unbeatable by any means, just apples to oranges.

  8. And a new bone stock Camary will pull the headlights out of it.
