If by interesting you mean funny. 8 litre v8 american muscle producing 165hp

I remember watching an episode of Wheeler Dealers where they took in a 1973 Camaro and Edd “I forgot more about cars than Enzo Ferrari ever knew” China swapped the engine, perhaps the only pure full engine swap on that show, and turned it into an absolutely awesome car.

Edd mentioned multiple times that the entire car was actually incredibly well designed by GM, superior to nearly all the much more famous previous Camaros…except the engine was complete trash.

Edd isn’t one to lavish praise easily. He said it handled well stock. Except the engine stunk.

He swapped in a 414 horse 383 Stroker. Lol.

Interesting? Maybe.

Desirable to own? No.

One of my main reasons for trading in my Subaru STi was how bad the fuel economy was for how little power it made. Compared to my new Camaro, I went from 300 HP at 20 mpg to 455 HP at 30 mpg.

Why would I find it fun to spend more money and burn more fuel, just to go slower? I find it far more fascinating just how much more power modern engines can make using far less fuel than older designs did.

Its cool until you own one and can’t even drive to work and back without having to refuel it.

Beast of Turin.

This is an interesting topic. I like the Pontiac 301 Turbo– 200 HP out of a turbocharged 4.9L V8.

GM engineers creating a 30 hp 20L v8

Those 70s boat anchors were in part to low compression ratios, smog trash on the back, choked up intakes, and so little of cam and crap heads that they’d only spin 4k to 5k rpm before floating the valves. They usually had some torque, but no rpm to make hp with.

I too, think everyone should be interested in the most efficient engines. You do not want a high horsepower, high revving, or many cylinder engines. Please do not buy them! let become super cheap so we know efficiency is superior.

How did they get so little horsepower out of v8 motour?

190 horsepower from an 8.2L V8

That specific motor in the caddy, I’ve always wondered what kind of gains would happen if you swapped out the heads for edelbrock cnc whatever run of the mill, intake manifold & carb.

The Cadillac 8.2L V8 made 375 hp and 525 ftlbs of torque when it debuted in 1968. It was all the emission restrictions that reduced power to 180 hp. It wasn’t designed to be inefficient. It’s like having restrictor plates on racecar engines to limit power. The engine can make more power, but the class rules state it can only have a certain amount of power.

I’d love to see a modern GMC cyclone have some engine tinkering done with a modern tuner

The interesting thing is how they managed to squeeze so little power out of such massive displacement.

Driving-wise, they suck. All the power of a Volkswagen 4-pot with none of the eagerness to rev. Plus, they must have come from the factory with an oil refinery, otherwise I don’t know how anyone was able to afford to fuel them.

How about an 8.4L v10 only making 645hp? heheehe
