The 58s from Gene Berg that cost a motza (and are out of stock) shift the power to a higher rpm range, and intact could adversely affect street driving in the common low to middle band experienced in street driving, by reducing air velocity.

Or is my humble research ill informed?
Are you able to kindly clarify this?

On another note: I believe webers ARE workable for a street engine. EFI or otherwise. The only limitation is the the time energy money and inclination one has to invest it them. For a car that's driven as infrequently as most Cobras are, I've placed them in the who could be farked category, for now. As I'm unlikely to drive them often enough and far enough to resolve and sort the issues.
That said I still do find myself tempted. :

Thanks in advance.
Yes all true, up to a point.

I agree the 48s are good for mild to slight aggressive street manners, but on a big engine will limit top end.

Here is some beautiful 58s of a fellow member:
