3.8 motor or DKS Darkside Rotor?
 

I was thinking of buying a new motor. Which one do u guys think would be better a 3.8 or DKS Darkside Rotor. I was gonna buy one of those or the DKS Fury Motor. Sorry if this has been posted before. Hope you guys can help, thanks.

**EDIT**

Oh yea and DKS i was just wondering about the FATF decals, it says that they should only be used on light colored cars. I was gonna use the DKS decals that come with it, and i was gonna put it on a black car is that ok? Thanks.

light colored car
 

I can get the decals for any color car, but I need the car color first as these decals are so thin, a dark colored car may dull up the color, if being used on a black car, they would have to be made for it specifically, if interested, let me know
