Review on Trans Dapt Performance 2039 Carburetor Adapter by Leo Torres

I had to drill new holes for the smaller carb base on a Dodge 318. So this one fits a chevy 2b as well not a mopar 2b then the rear is domed and the new ford 2100 has a flat rear. You can use a heater plate to seal it on the bottom of the carburetor. The widely spaced factory air vents dangled on the Dodge's air intake and had a vacuum leak. Glad I changed it, I'll stick with it. I will use it for some others in the future. If all you need is an adapter for Holley 2b, this is the best option you will find, but it will not work with other applications.
