 4-1-5-0. Let's see if we can get this in quick. Larry, you're on the Under the Hood show. I got a 98-99 Chevy Tahoe with a 6-0 in it. The former owner apparently took it upon himself to cut up. It has no catalytic converters, apparently. I'll double check on that. But it also has a cold air induction. And it seems to be a little lacking in performance and gas mileage and stuff. But Tahoe's are kind of famous for that.
