415HP from 318ci IS POSSABLE!!
I don't think its an issue of "318 haters". Everyone is giving you an opinion, and I would have to agree. If you're just looking for HP numbers, then yes, the Engine Masters 318 you're looking at might be fine. But like Ramcharger, Fishy, and most others are saying, that 415 HP is up at the higher end, so if you're drag racing, fine! But if its a casual street driver, low end torque is what you need and you probably will seldom see your engine spinning high revs. Everything else above 3000 is wasted, unless you want to be able to brag about your engine's numbers. My two cents...
