    67100C is rated 5.0 out of 5 by 3.
    Rated 5 out of 5 by from a great product I bought this several months ago I also bought the billit baseplate and purple metering blocks because I race my car every chanch I get to, but I can still drive it on the street with the race metering blocks in it. I ordered all the parts and built it myself it was super easy. This carb is very adjustable and easy to set up and it made my 427 come alive I picked up a lot of HP over running a 750 double pumper. My 55 chevy will pull the wheels up about a foot now when I come off the line.

    Rated 5 out of 5 by from Quality part I bought this to replace the main body on my Mighty Demon 750 because the venturies melted in a back fire. I waited 4 months for Holley to send me a replacement and never got it. So, I chose the ProForm, and I am very pleased with it. Everything swapped over just fine. The only thing I didn't like was that the description said there would be instructions and a jet kit. There were no instructions and only a replacement set of jets. But overall it worked for what I needed it to do.
