10k: F=ma: 1970 Pontiac Grand Prix 455ci

If you've been paying attention recently, you may have noticed that we have featured a bunch of swaps recently.  There really isn't anything in the water, it has just been a barrage of well priced engine-swapped MGs, Starlets, and they just seem so tempting.  A swapped sleeper is certainly a cool way to do business, but sometimes you just want 455 cubic inches of OEM power to shred the tires in style.  Find this 1970 Pontiac Grand Prix SJ currently bidding for $7,200 reserve-not-met with $15,000 buy-it-now on eBay with 5 days to go.

The second generation Pontiac Grand Prix was released under the supervision of John Z DeLorean who was Pontiac's general manager, and it falls squarely at the beginning of the malaise era.  The Grand Prix is a big heavy boat of an automobile, but its engine is a monster from the era before emissions laws choked the fun out of 'Murican land yachts. 

Under the hood of this Grand Prix is a 455 cubic inch (7.5 liter) V8 that pushes a healthy 370 horsepower and a murderous 500 ft-lbs of torque.  Even with a curb weight pushing 4000 lbs, this car should pull like freight train at medium speeds. 

See sellers buy-it-now price is optimistic for this car, and the last time it went through the auction process, it failed to meet reserve just above $10k.  Will the seller drop the reserve and let it move on, or will we see this beast again?  tips@dailyturismo.com


  1. The '70 Grand Prix SJ is a tire shredding mutha! I've driven a couple of the '69-70's and they have an astounding amount of torque behind them. The cars are HUGE, but because they weigh so much, they actually hook up pretty quickly.
    All the ones I've driven have a cool feature in the shifter which operated a lot like the Hurst dual-gate without the two separate gates. I tried to find a reference for it all line, but...essentially it was spring loaded to one side so that you could hold it in first, push it up into 2nd where it would hit a mechanical stop,same thing going from 2nd to third.
    These were geared pretty short. Most of them would be 0-45 in 1st, 45-75 in 2nd and whatever you could get out of it in third. Friends who were used to less performance just named those gears 'fast, faster and dear Lord we're gathered here together".

  2. I'm with Hunsbloger—the 1969-1970 Grand Prix SJs were big, mean, tire-smokin' torque machines, and I’ve always wanted one. The 455 HO (w/370 hp and 500 lbs-ft) was new in the 1970 SJ, while the 1969 SJ had the 428, in two flavors—370 hp and 390 hp (HO). Either ’69 SJ 428 was the way to go in these—you gave up some torque to the 455, but more than made up for it with the 4-speed manual that a handful of '69 SJs left the factory with. Now THAT’S the car to have.
