Wao, 4x1700 injectors? is that for alcohol or gasoline? cause if its for gasoline im almost sure you wont be able to get them to idle below 2000 rpms, they are so big they wont atomize fuel properly at lower rpms.

What is your hp aspiration? what kind of work does the engine have? I would suggest you get a pair of 850cc for the primaries.

the guy said it was streetported. I would like to keep the secoundaries but ditch the primary's

Yes, that is what i said, keep your 1700 secondaries, and get a pair of 850 primaries. I also forgot to mention, if the car belches out black smoke and smells like gas, its probably dumping too much fuel so its in need of tuning, and yes, your F10 will be able to work perfectly for it. I personally recommend the use of an ECU that controls both timing and fuel, but if that is what you want to work with it will serve, specially if its a drag only car.

You're plugs will probably need to be changed too. For that kind of setup i would go with the BUR9EQP in both leading and trailing, tune it right, and then swap plugs and use the BPR9EIX which are ididium, BUT! and this is a big BUT!, the car has to be tuned perfectly when using the iridiums, if you have too rich a mixture they will go bad instantly.
