Video: A Judd V8-powered Alfa Romeo 4C just might be the wildest hillclimb car

Shoehorn a twin-turbo LS7 V8 into a modified Lotus chassis, and you get the Hennessey Venom GT.

But what do you get when you shove a Judd V8 into an Alfa Romeo 4C? This insane hillclimb racer, apparently.

Dubbed “MG-AR 01 Furore” by its creator, Marco Gramenzi, the car is good for more than 650 horsepower, can rev upwards of 11,000 rpm and weighs less than 1800 pounds.

Very badass car.

But it's pretty amusing that he plastered the car with Alfa racing logo stuff even though it's less of an Alfa now than it used to be.....  

Now if that was one of the old V10's that were used for the prototype 164 racer back in the 90's, that would be very different.

I recall seeing a video of an e36 BMW hillclimb car with a Judd V8 engine.  If nothing else, just the sound of those things is amazing.

I've never seen a Judd swap that I didn't love

I think this is the Hillclimb version but any Judd especially the Judd HK engines hold a special place in my heart having been based on the BMW S65's.
