Stock injectors just make it with this setup, but depending on the intake and size of the pulley the factory pump will not be enough as they start to drop fuel pressure and air-fuel is not able to be controlled around 630-650BHP.
63lb Siemens or ID850's are two great options. The 63lb will support 650RWHP with ease.
