Is the 383 a better engine, or does the 440 just have more displacement?

It was cheaper to build my big block, my brothers been down the sb stroker road now going big block in his 67 barracuda.
Oh, I agree! I have nothing performance for a small block, I would have to start from scratch. I have one 440 based stroker, parts for another, and a nice 400 block that would fit in my 67 barracuda nicely, stroked to 512.
