It just seems like it would be easier just to put the camshaft over the clinder heads and make a 4v/cylinder DOHC motor.

Here is the patent for 3 valve with Di

and here with 2 cam in block and DI (probably something similar to XV8 concept engine)

So it can be done. Question is will Gm do it..maybe they'll do normal 2v with DI LS engine for trucks, chevy, pontiac etc and special 3v DI for cadillac.
