when is it start to be required to upgrade the fuel rails?

[ttocs]

with everything else I have going on with my rebuild/build I have never given any thought about the fuel rails. Will adding the vortech require a bigger rail? Is there rule that when you go above a certain size fuel injector that you need to upgrade the rails or some other way other then when it starts to run lean? After asking around to the motor/supercharger people I know and trust I settled with 42 lb injectors. So am I past that point already or close enough that I should go ahead and do it anyway?

Scott i assume your still running a stock block? If so i wouldnt be to concerned about rails unless you plan on pushing your block to its limits as the stock rails will support 500-550hp. Not sure what your intended goal hp wise but if im not mistaken your using 42# injectors wich will be maxed out before the rails again another reaspn not to worry about them. Now if your going for a cleaner look then by all means upgrade otherwise you have more important things to consider than the rails maxing out.

cool thanks I thought I read somewhere they were good up to 400 and that is about what I am aiming for at the moment.

ah maybe that is what I heard as I don't have any experience with foxes myself short of a stereo/alarm/remote start but thought it was closer then that. Thanks again.

They are good for quite a bit. I put 560 to the wheels with stock rails
