Much better than other alternatives out there
By Daytona955
If you are trying to adapt a Holley Pro-Jection 2b kit to a 2 barrel manifold, this is the only way to go. I tried another adapter and even with tons of grinding and porting it would not fit 100% correct. This adapter fit perfectly on the 2 barrel Holley 2300 manifold and the projection bolted right up. The 4 bolts for the manifold were a little tight, but just make sure to start them by hand first before tightening everything down. On the other adapter I was having issues with a vacuum leak no matter what gasket I used. This one there was no leak at all. As a side note, on several sites it said that it did not come with gaskets or hardware, but this kit came with both gaskets (top and bottom) as well as the necessary 4 bolts to bolt it down to the manifold. Overall I am quite satisfied with the product.
