As much as I know the K makes some serious power and has a lot of potential... I'm still a B series lover. I think it looks better, its cheaper/easier to get parts to build and IDK I just like it. B series was the foundation and I'm with it till the end. Sure I'll probably build a K swap in my life but I love the B. Its all up to the person buying it. I just hate the K series bandwagon where now if its not K swapped its not cool and everone else is below them. HP is HP. Now for those that say because I dont have a K i'm hatin. I know what K series are like they ride out for sure in chassis other than what they came in.
