I loaned mine to the dyno shop that I work with. They've dynoed a bunch of higher hp engines with that carb over the last couple of years. It works great and it usually makes more power than a customer carb. It even makes more power than the big Braswell carbs that most customers have. (customers are mostly circle track guys).

But the carb hasn't ever been on the street or down the track. I might put it on my car this summer. I currently have a 950HP on my car so I guess it would be comparison. My car has a 512 inch low deck and I don't think I need the true 950. But your car might be able to use it. My engine is big, but it is a very mild build with a hyd roller cam and factory HP exhaust manifolds.
