Badbowtie247 Posted May 21, 2014 Report Share Posted May 21, 2014 I'm taking the motor out of my 03 return style system this coming up winter and doing a 408 and I was wondering if it's okay to swap in a bigger fuel pump for more flow now with what I have done with it 224/230 cam 114lsa 40 lb injectors being a problem just basically to have it done so I don't have to do it when I'm ready to pull the motor.

Link2603 Posted May 21, 2014 Report Share Posted May 21, 2014 Yeah it should be no problem putting in a bigger fuel pump. You still running the stock regulator? Sent from my iPhone using Tapatalk Quote Link to comment Share on other sites More sharing options...
