4cyl to 5.0 brakes.

I was wondering if I could use the 4cyl brake lines with the 5.0 mastercylinder and booster. Is it possible? Is it gonna affect the braking perforamce? I plan on running the 5.0 discs and the 8.8 rear end. I see that the rearend line is different on the two, but I am understanding that if you run dumps you dont have to worry about the line, which I plan on doing. If I were to switch to 5lug 4 discs would I still be okay with the 4cyl lines? So will the 4cyl brake lines hook up to the 5.0 parts; is my main concern. Thanks guys.
 
same brake lines. my 86 5.0L has 4 cyl brakes basically because in 87 they upgraded the brakes to bigger and ran the 86 5.0L stuff on the 87 4cyl cars. i have a rear end from a later model 5.0L. i believe a 90 and i didn't change anything with the brakes i just installed rear end and hooked up brakes.
