340 vs. 440? (Help)

I have had small blocks A Bodies,4 speeds and autos.Ran good alot of fun.
But the real fun started once I got my 383 4 speed Dart running.The 383 Dart handles pretty well also but the small block cars handle a little better.I only really notice the differance in handling when I go around a corner sometimes.With a Big Block it will cost alittle more and the fit will be tighter.If you can live with that it is WELL worth it.
