SB stroker guys - what fuel line diam and what carb?

The small stuff adds up FAST.
There are cheaper routes so don't let my spread sheet scare you.
 
3/8 aluminum line front to back, Holley blue pump, Proform 750 dp.
 
This is what I used, 2 -8 lines from the cell to 2 Holley blue pumps with Moroso 18 psi bypass springs, 3/8 aluminum lines out of the pumps to 2 Fram HP-40 fuel filters, 3/8 out to 2 Holley regulators and -6 to each bowl of the carb. I know this sounds like overkill but I think this thing might actually be running out of fuel on the top end. The carb has 90 jets in the front and 93 in the rear. I may upgrade this soon to -10 line to 2 Holley black pumps and -8 up to the regulators but first I think I'm going to try some larger needle and seats.
 
On my 408 stroker that you see in my sig pic, I'm using 1/2 (-8) stainless hardline from fuel cell to regulator, to carb. return lines are all -6. I'm using a 750 mighty demon carb.
 
5/16 was lacking on the top end, I had to go 3/8 on my 416
