1965 Corvair Corsa: Corv-8 Conversion


Here’s a throwback to a different era: “For $1,000 and 40 hours of work, you can have one!” That was purported to be the marketing jingle for the Crown Conversions kit to transform standard Corvairs into a V8-powered rocket. This 1965 Corv-8 here on eBay seems like a cheap entry into a fun, fast and even somewhat historic classic car. The founder of Crown Conversions cut his teeth performing engine swaps with vintage Volkswagen dune buggies driven by Corvair powerplants, and the rear-engined Chevy represented the next logical place for him to work his magic: sticking a Chevy small block in the already toss-able Corvair. While this car will need a proper inspection before it rips down the road once again, this is a blissfully simple collection of parts with plenty of junkyard SBCs and Corvairs available to pillage from. Did any of you perform this conversion in your backyards back in the day?

    I had a 65 Corvair Corsa – among others – it was a neat car. AIR – it was the 140HP version with extra gauges and suspension tuning – I think it had quicker steering ratio. Stock it ran well and handled fairly well. I remember the Stingers that ran SCCA back then… still a few around at Vintage Racing events.. For someone with the necessary body and mechanical skills this could be an interesting Retro-Mod for weekend cruises..

    Of course a pure stock, original Corsa would be worth much more..

    Could be a $5000 rocket if you are a little handy—go stoplight lurking…
    would be nice to have more info…

    I also had a 140hp Corvair, 4 carbs. It was pretty quick. This would be a rocket, but a fun rocket.

    That 327 has the big harmonic balancer, which makes it a 340 horse or even 375 horse engine which means: Steel crank, forged pistons, 30-30 cam, fuelie heads etc. That engine could be worth $15,000 on up.

    Oh hell yeah – what a sleeper. Move the radiator to the front for better cooling and go Mustang hunting…

    Actually I did assist on a Corv-8 conversion back in the day in Montana. Moved away before I saw it completed. Wonder if it was.

    Back in the early 70’s a friend built a 66 Monza mid-engine. He made his own mounts, brackets, adapter plate to trans from pictures of the Crown stuff. Only his power was a 392 Hemi, out 60 to 405, wild cam, custom headers. Rocket was a gross understatement. Seriously, the stripes on the road were solid and the telephone poles looked like a picket fence. 150-160 mph was a piece of cake !
