That reminds me of a friend’s V8 Vega. It twisted the unidbody and he actually had to cut the doors at the front fenders so they would open and close which meant it was soon un-drivable. It moved though.
The Kamback, I built the engine for a friends, it was a cool car. Unfortunately, it needed a windshield and the Kambacks was different than a regular Vega (how stupid is that?). He was poor as I was so we ended up putting the window (because we bought the wrong one and they didn’t have the correct one so they said) in and it hung over one side. Not a great rig bit it lasted as long as he had the car. It was like a modern version of a 55 Nomad, OK, so that’s stretching things but it was a cool car.
The Vega was good for laughs with 300 h.p. We stiffened up the rear suspension with additional coil springs and inflatable air bags in the coils. The ride was very bad; we also put in a modified turbo 350 automatic tranny with a 3500 rpm stall speed torque converter. The engine ran an Edlebrock single plane intake with a 650 cfm Holley double pumper. The dang thing would lift the front end about a foot off the ground upon takeoff if we revved the engine up with the front brakes locked. Eventually, the rear end blew up and on one run the right front upper ball joint broke clean off. Too much power and too little re-engineering. And we also cracked the windshield because of the torque which caused body flex. I figured at that point it would have cost another $10 grand to make the thing work.
About ten years later we now have built a 1972 Camaro SS with a 410 cu. in. Chevy big block. At least the Camaro is the proper platform for a 400+ h. p. engine.
