Perfect fit, includes gaskets!

I used this for a 1955 Buick Nail head and it worked perfect! Picture doesn't show gaskets, but I was relieved to see that they were included. The only other thing to mention, is that I had to center the butterflies before tightening the carb down, it's close, but it works great! The car never run so good.

Problems with quality

One tab broke and another cracked when installing with only seven to nine pounds torque. Casting was bad with several stress areas. The piece was not flat with several low spots on both sides. Also burrs that needed to be removed. Wish that Speedway offered a better option, maybe billet? They are sending a replacement. Hope this one turns out better. All the other parts purchased along with this mounting plate are great.

Great fit for EARLY Rochester 4-Jets. (Early to mid 50's GM) The flat head socket head screws allow you to screw the adapter to the factory manifold. There is another adapter that says it works for Rochester but not the early ones. Screw down to the manifold and the carb (edlebrock 1406 in my case) bolts right up. Good quality and fit, hardware and the included gaskets are good quality too. Used on a stock 1955 Cadillac series 62 w/ 331.
