fuel system upgrade ??s

[gtospeed]

i am running a front mount turbo kiton my 06 gto with 60lb injectors -8 feed lines and arromotive rails and fpr will a single walbro 255 be enough to support 8psi and hopefully low to mids 500s. also can some one give me the center to center distance of the rails so i can make my crossover line to go between the aftermarket rails.
