As a Porsche purist, I agree.
But the LS1 does make sense; it's an engine that's a LOT cheaper, easier and cheaper to modify, and at the same time weighing about the same as the 930 engine.
For the average person:
To get 600hp from a LS1 engine costs about $3500 in mods.
To get 600hp from a 930 engine costs about $15,000 in mods.

I would still never do a LS1 engine swap in a 911, which will lower it's value. However, I would do one in a 944/968, which when done professionally will actually raise its value.
