Stroker/blower combo questions

I am running an 06 stage 3 roush car right now with a few simple changes, but after getting beat up on really bad ive broke down and ordered a livernois stroker 298 ci shortblock, stage 3 heads, a set of comp cams camshafts and a hand full of other minor parts my question is if i stay with the roush blower should i change the fuel system, or just leave it alone? every place i talk to tells me differnet things so i want some more opinions on it while the car is apart. im on the fence about just getting rid of the roush blower for a large procharger setup or a set of twin turbos but right now im just thinking about the fuel system that would b eneeded to run this setup. the roush injectors are 38 lbs/hr and the setup uses the stock mustang gt fuel pump any help would be good

they wouldnt say what i should do with the fuel system. talked to them about it saying that im putting a livernois stroker motor into the car, and that i need to know what fuel pump, injectors are in the car and what the fuel rails where good for. they told me that the injectors where 38 lbs/hr, and that the pump was stock and the rep i spoke with wasnt to sure what the rails where good for. besides the roush blower being a m90 is a small displacement blower, but i might hold off for a week on ordering a blower as theyve got a 2.3L m140 tvs blower setup coming out for the standard 4.6s that they used on the p51 cars

it was a slightly modded 07 Z06 that kicked my ass. the worst part is its my old man that owns the car so i never hear the end of it
