Right off the bat with that kit you are gonna need a fuel regulator that is boost referenced. I will link parts list below of what you will need, that is the same setup I was gonna run on the vega I was building. there is a good video I will link to about it as well. Road kill guys did a video about it. one thing to note is that they get a good bit of belt slippage. it is a good setup right out of the box and will work on your 350 no problem it is the supporting mods that get you.
Personally read this it explains about the regulator you need and should let you know why.

First off you can mod a holley 12-803 regulator to do boost but it is not my first choice, although I have seen it done! This is the cheaper dead head regulator style.
This one is what some low buck guys are running. There are many others most are return style.

If you want to stick to a mechanical fuel pump then I would look into this one.

then it is just a matter of rejetting the carb. I would use a wide band 02 meter for that though. Reading the plugs with a blower is not the best Idea but it does work.
If you just want bolt and go then I would get a weian 142 blower instead it is a roots and does not require a regulator because the carb does not see the boost so no need to raise fuel pressure to over come boost.still would upgrade fuel pumps to atleast a 110gph even for a roots kit.
