Cadillac LSA-Swapped 1968 Buick Riviera

It’s no secret that I’m a fan of resto-mods, as I cover plenty of them every year at the SEMA Show. The combination of timeless styling and modern turn-key reliability is a formula that many people find appealing. But as is so often the case, people tend to overdo it.

I understand that if you’re going to upgrade the engine and build a car, you’re also going to do better brakes, suspension, and fix up the rest of the car. As a matter of personal opinion, I am conflicted when I see an old car with 20-inch billet wheels, fender flares, and massive disc brakes. Are you trying to build a muscle car or a modern race car? It looks a bit odd to me to see carbon fiber air dams and projector headlights on a 1960s car.

With this 1968 Buick Riviera, they really got it right.

I spotted this car at the monthly Cars and Coffee gathering in Scottsdale, Arizona. The original engine has been swapped with a supercharged 6.2L LSA V8 from the Cadillac CTS-V. With 556 horsepower, it certainly packs more power than the original engine.

And again, there is that turn-key reliability. Modern engines can run on ethanol-blended fuels with no problem (ethanol blended fuels are sold in Maricopa County). Modern engines don’t need to have the valves adjusted every 30,000 miles. You don’t need to let it warm up on a cold morning. You don’t need to worry about vapor lock on hot summer days. You just get in, turn the key, and cruise.

This car appears to be set up as something of a sleeper/cruiser. It doesn’t have a wild paint job, crazy wheels, or anything to indicate that it’s packing a serious wallop under the hood. From the outside, it just looks like a clean, restored classic car. Even the exhaust tips with stock-looking turndowns are present.

I’ve got to hand it to the owner on this Rivera for doing it right by not over-doing it. Well done.
