383 vs 360 in an A 68 Cuda

Go for the wow factor of a big block in an A body. I am going to do a 383 in my 68 B'cuda ragtop (original 318 car) in a few years when I build the car. I have choices. I have a complete 69 hp 383 out of a go-fast optioned Fury, and I have a complete 63 or 64 383 out of a Newport. Also have a 440 crank and rods from a motor home laying around. My initial plan is to stroke the 63/4 motor with the 440 crank. Time will tell. I also have 2 360 LA blocks I could build.
