Not Ranked
I drove an SPF with a Roush 427W that was originaly a carb motor but had been replaced with a Hillborn (sp) injection system. I think the Carb motor 427's that I drove had more pull off the bottom than the injected motor. I think the cam profile on the injected motor might be different and this might be the reason that the injected motor did not feel as strong to me. Maybe you should consider a different cam if you go to injection?
