this is the style i need correct? and this should suffice for 420~ horsepower at the wheels?

 

anyone?

 

Yes those are the right style of injector As far as if they will support your hp goal Im not sure Im at 428RWHP and I am using Nasty Performance Stage 1 Fuel Kit. Its good for over 600 at the wheels. So I know if I decide to go power adder my fuel system will be able to handle it. You could also ask about this in the fuel section. There are a lot of extremely knowledgeable people in there when it comes to this type of thing
