Best Bolt on and Go Carb for mild 440

Im looking to replace the carb on my 73 Cuda which is running a mild 78 440 with eddy performer rpm and Purple cam not sure the specs.. Pretty Choppy though..
I have a Carter on it which works but not too impressed with the cold/hot starts and the response.

On My 73 Runner 340 I put a Speed Demon on and hated until I had a engine builder tune it now I absolutely love it on that car but I am looking for something a little more simple to tune that I can install and drive..

Im thinking 870 Street Avenger but open to advice..

Thanks!
