Allows my 1957 Chev to have a new Carb.

My 1957 Chevy. 283 has a different manifold than later small block Chevy's and this adapter makes it possible to use a new Edelbrock carb. on my 59 year old manifold. Adapter fits great is complete with hardware, gaskets and looks good also. Talked with two customer service Reps. both were very helpful. Used two day shipping which got it here in two days and was cheaper than other suppliers standard service. I am very happy.

Usable for the price

Mounting hole needed modification. The countersinke did not fit the suoolied hardware and were slightly out of position. Also the mounting holes were not drilled through. I was lucky enough to have access to a machine shop since I don't believe this could be done with just a drill. I also replaced the hardware since the fit was very loose. The only hardware I used from the kit were some mounting nuts that fit into the pockets at the carb mount. Overall the price is ultamately the thing that makes this a worthwile product.

The only complaint I have is that the manufacturer did not drill out the 4 inner bolt holes, but that certainly isn't a deal killer.

This base plate successfully lines the Edelbrock 1406 ports to a 4GC carb base pattern. Not to mention its aluminum and low profile. Comes with everything needed; hardware and gaskets! -used this on a 59' 409 and 65' 327 intake, probably will work on 283.
