Do you race?
If you do, then keep your current motor.
If you dont, quit pissing around with all of the high dollar, high HP parts. Just build yourself a stock motor with cheap, easy to obtain parts, and run it that way. It'll be dependable, economical, and still fun to drive. Stock Mopar motors put out plenty of HP.
I just dont understand the guys that build a balls out, high hp motor, then all they do is take it to cruise-in or run a couple laps around town. I think they just like to brag about how much useless horsepower they have. I have a friend that has a hemi pushing over 1000 hp. He never takes it anywhere but shows, and constantly complains how expensive it is to operate. All of my cars have stock, or close to stock motors, and they're more than enough to have fun with, and I can afford to drive them.
