My two cents are a little late but Solex cams will work and work well if the engine is tuned by a competent mechanic.
We have 3 or 4 MFI engines with Solex cams and the customers love them.
BTW: Solex cams and E cams are nowhere near the same.

Here is a 2.7 MFI with Solex cams. The cars screams and the customer (who tends to be quite meticulous and owns 3 or 4 Porsches right now) has no complaints.
