That's the engine out of the '08-'13 Corvette, for those unfamiliar with the code.
Since this is not the first time we've seen an American V8 in a Japanese drift car, we know that you're going to find it a bit odd. And some of you are going to get seriously bent out of shape about it. This time the car is an S14 Nissan Silvia, a car which, in its US-Spec form - the 250SX - got engine swaps all of the time. Of course, the Japanese Silvia didn't need an engine swap to be a great drift car, making this a bit of possible overkill.
We suspect that we might already know the answer, but what do you think of this. Is it blasphemy?
