Maybe 3k miles and about 30 1/4 passes on it.

Have had 2 carbs from these guys now and man do they deliver. This one I'm selling replaced one I had fiddled with for years. I put it on top hooked it up and will never buy an off the shelf carb again. 1/10 in the quarter imidiatly and cured my cars hesitation, cold starts were nowhere near as terrible as they had been. It drove just as fantastic on the street as it did when I pulled into the staging lanes the first time. The one I'm currently using had sat on the car for 6 years before I turned the keys again finally and after a battery and new distributor it started as if it had been sitting for 5 minutes. Pro systems just kills it!
