365 or 408?

Well I guess I should have specified, im willing to spend anywhere from 2000-2500 on the bottom end, crank, rods and pistons, rings bearings ect. I already have my top end all paid for and ready to go, so I'm not including that in the price. But why am I finding that a rebuild with the stock crank (turning and balancing) and new pistons is quite similar in price to a stroker kit? I've found some scat kits for just over a grand, would need balancing though. Even if my current heads won't give me the kits full potential I can always upgrade my heads later on.
