    97-1C28Q is rated 3.0 out of 5 by 2.
    Rated 5 out of 5 by from Works as it should I bought this converter as it was the only TH350C 3000+ stall I could find. I've ran it for over a year on the street with no issues. I have a 425 HP small block in front of it. It's definitely pricey, but I'm happy with my purchase.
