AJ's Opinion; what size SBM do I need

Again, it's not that someone is say'n a 318 is better than a 360 or 408 or 440. I think it's simply if someone wants to do a little something to their 318, what's wrong with it?? It could be not everyone is hoping to run a 11.32 with their daily driver. Maybe a nice running 318 that cruises on the highway and will run a 14 second 1/4 mile is all they want... especially if they are on a fixed 500 dollar budget.
