I've a threaded shell Does that mean your frame itself has an Italian or BSA/English threaded bottom bracket shell? And you want to use a BB30 crankset on it?

There are some solutions in forms of bottom brackets designed to run 30 mm cranks in a threaded BSA bottom bracket shell. The deciding factor is the spindle length.
Searching the net for "bb30 crankset in bsa frame" gives e.g. this:
Threaded to 30mm Angular Contact BB - Black
Our solution for running a 30mm spindle crankset in a BSA threaded frame.
Notes:
For use with 30mm diameter cranks with a spindle length of at least 104mm. Will not work with standard BB30 cranksets.

This is 100% correct, the limitation is the spindle length. I run 30mm THM Clavicula SE cranks on a THM BB on a BSA frame. I was also going to run FSA Cranks BB386EVO Cranks on a FSA MegaEvo Road BB that also work.

That won't work, as the threaded bottom bracket shell simply isn't large enough.
BB30 cranksets have a 30mm spindle diameter. Per Wikipedia, the maximum internal width of an English or Italian-threaded bottom bracket is about 34 mm. Those few millimeters are not enough space for bearings.
I also think the BB30 crankset spindle will be too short.

But bearings can be in external cups and as such won't be limited to 4 mm
– Grigory Rechistov
Dec 14 at 18:38
Yep, BB30 spindles are designed for BB shells either 68 or 73mm wide, so you can’t have an external bearing solution.

Dec 14 at 19:25
The bottom bracket is more than large enough. The issue is only the spindle / offset on the crank.

Dec 14 at 20:49
@sjakubowski The bottom bracket is more than large enough. Seriously? What kind of bearing fits in the 2mm or so between the 30mm spindle and the 34 mm bottom bracket shell? Unless the OP already has a crankset designed for BB30 and outboard bearings, there's nowhere to put the bearings. It "won't work".

Dec 14 at 21:10
I didn't say it would work, I said the reason you mentioned is incorrect. I gave examples of 30mm diameter cranks working just fine on BSA. If you replaced the spindle on a BB30 crank with a longer one it would work just fine.
