Anybody know sources for larger aftermarket fuel rails for my 1996 460 efi? It is being rebuilt but with much more displacement, 557 cu. It is map but I am changing to maf, but I'm sure I will need to add some fuel volume in rails and injectors. Also the originals are pretty boring looking. I can't seem to find them, I guess I am looking in the wrong places?

 

I'm no expert, but even with the increase in Displacement, I don't believe you should have to change fuel rail for a larger one. You would simply be looking @ larger fuel injectors, depending on setup. If I'm wrong or misspoke, I hope someone corrects me. I always learn something new here on FTE..

Depending on how much you need to deliver, will depend on injector size and whether or not your stock fuel pump can keep up @ that specific rate for the specific injector size. Even going to MAF, you may have to get a computer that is MAF compatible and then it will have to be tuned. Have you checked Summit, Jegs, or Ford Racing for a new fuel rail?

Some other members should chime in with info. Have you posted in the Big Block forum with help? Just an idea....
