Junkyard Find: Small Block Chevy-swapped 1969 Jaguar XJ6

The Series 1 Jaguar XJ, built for the 1968 through 1973 model years, sold fairly well in the United States but became a rare sight in self-service wrecking yards well before the 20th century was through. I photographed this ’69 in a Northern California yard all the way back in 2007, when I was busy harvesting clocks for my collection and gauges in general for my team’s 24 Hours of Lemons Volvo, and I think it’s time to share them.
Jaguar straight-sixes weren’t horribly unreliable, at least by the standards of the 1960s, but the good old Chevy 350 has always been tantalizingly affordable when the Jag’s original engine gives up. This was a very, very common swap, given the Jaguar’s spacious engine compartment and the overabundance of cheap small-block Chevrolet engines going back to the 1950s.
The shadow of the yellow-on-blue California plate, drawn in road dust, remains visible. The first year for the blue plates was 1969, so this may have been the car’s original license plate.
Would you trust any of the Lucas– or Smiths- built electrical components you see here? As I recall, I bought the clock and voltmeter, neither of which worked.
It was beat-up and showed ample evidence of liberal application of body filler, but it didn’t seem rusty. Worth restoring in 2007, with the Great Recession just getting into gear? Probably not.
It’s better to imagine a car like this when it was a very luxurious status symbol, not what it became during its decline-and-fall years.

    A lot of the transplanted XJs I've seen over the years, going back to the '80s, ran Buick 400s rather than SBCs. Was this because of the displacement versus physical dimensions?

  • Greg Greg on Jan 23, 2023

    Yes, here in Australia too in times gone by there were people in the Jag club who had fitted Buick 400's & 454's to both series 1 xj6's & also to the bigger mk10/420G's as there is plenty of room and the big block Buick v8's are still lighter than the Jag 6 cylinder!!

  • CM Korecko Cadillacs, traditionally have been opulent, brash and leaders in the field; the "Standard of the e World".That said, here's how to fix the brand:[list=1][*]Forget German luxury cars ever existed.[/*][*]Get rid of the astromech droid names and bring back Seville, Deville, Eldorado, Fleetwood and Brougham.[/*][*]End the electric crap altogether and make huge, gas guzzling land yachts for the significant portion of the population that would fight for a chance to buy one.[/*][*]Stop making sports cars and make true luxury cars for those of us who don't give a damn about the environment and are willing to swim upstream to get what we really want.[/*][*]Stop messing around with technology and make well-made and luxurious interiors.[/*][*]Watch sales skyrocket as a truly different product distinguishes itself to the delight of the target market.[/*][/list=1]
  • FreedMike Not surprisingly, I have some ideas. What Cadillac needs, I think, is a statement. They don’t really have an identity. They’re trying a statement car with the Celestiq, and while that’s the right idea, it has the wrong styling and a really wrong price tag. So, here’s a first step: instead of a sedan, do a huge, fast, capable and ridiculously smooth and quiet electric touring coupe. If you want an example of what I’m thinking of, check out the magnificent Rolls-Royce Spectre. But this Cadillac coupe would be uniquely American, it’d be named “Eldorado,” and it’d be a lot cheaper than the $450,000 Spectre – call it a buck twenty-five, with a range of bespoke options for prospective buyers that would make each one somewhat unique. Make it 220 inches long, on the same platform as the Celestiq, give it retro ‘60s styling (or you could do a ‘50s or ‘70s throwback, I suppose), and at least 700 horsepower, standard. Why electric? It’s the ultimate throwback to ‘60s powertrains: effortlessly fast, smooth, and quiet, but with a ton more horsepower. It’s the perfect drivetrain for a dignified touring coupe. In fact, I’d skip any mention of environmental responsibility in this car’s marketing – sell it on how it drives, period.  How many would they sell? Not many. But the point of the exercise is to do something that will turn heads and show people what this brand can do.  Second step: give the lineup a mix of electric and gas models, and make Cadillac gas engines bespoke to the brand. If they need to use generic GM engine designs, fine – take those engines and massage them thoroughly into something special to Cadillac, with specific tuning and output. No Cadillac should leave the factory with an engine straight out of a Malibu or a four-banger Silverado. Third step: a complete line-wide interior redo. Stop the cheapness that’s all over the current sedans and crossovers. Just stop it. Use the Lyriq as a blueprint – it’s a big improvement over the current crop and a good first step. I’d also say Cadillac has a good blend of screen-controlled and switch-controlled user interfaces; don’t give into the haptic-touch and wall-to-wall screen thing. (On the subject of Caddy interiors – as much as I bag on the Celestiq, check out the interior on that thing. Wow.)Fourth step: Blackwing All The Things – some gas, others electric. And keep the electric/gas mix so buyers have a choice.Fifth step: be patient. That’s not easy, but if they’re doing a brand reset, it’ll take time. 
  • NJRide So if GM was serious about selling this why no updates for so long? Or make something truly unique instead of something that looked like a downmarket Altima?
  • Kmars2009 I rented one last fall while visiting Ohio. Not a bad car...but not a great car either. I think it needs a new version. But CUVs are King... unfortunately!
  • Ajla Remember when Cadillac introduced an entirely new V8 and proceeded to install it in only 800 cars before cancelling everything?
