SN 92 fuel pump

Hi, I'm intalling a SN 92 in a 66 mustang but I dont know what is the correct fuel pump to use, i read in the paxton page that I can drill/tap a fitting in a mechanical fuel pump and that will work as a boost reference. Is that correct? or is there a pump already whit a boost reference?
The supercharger have a 3.5" pulley and I have a 7.5" crank pulley as I read in an other post this is too much for the supercharger, what size of crank pulley do you recomend?
The engine mods are:
MUstang 95 block with stock crank/pistons
TFS stage 1 cam
GT40P heads
Edelbrock Air Gap Inake
holley 650 dp carb
Mac headers
MSD 6A box
What sugestion you have to improve the setup for the supercharger?
Thanks
