If Corvette is going to eschew pushrods... and really become something for a new generation to latch onto...
It should go mid-engined at the same time... and make the break from one generation to the next as stark, and thus clean, as possible.
If they are going to raise the ire of traditional corvette fans... then the corvette should truly be non-traditional in every respect.
Changing only ONE thing that Corvette has been known for all this time... will only piss people off.
Kind of like making a 4-door turbo-boxer Subaru WRX... with 2WD. One major change on a platform that has expectations attached to it. BRZ being 2WD is much better as a different car, than if they had made one change to an existing car that people know for being a certain way.
