The LS engine family is the way to go.
It's true you can get motor power and efficiency using a LT but the price to get them running is likely more than twice the LS family. I just looked into a LT wiring conversion, for a friend, and just the wiring was over $3K. That's without a tune. He plans on running a stock motor, no tune required. Putting the harness money into internals (cam and heads) on a LS will likely get you more power for less money. The holly grail, more reliable power for less money.

The LT engine can run higher compression, which equates to an efficiency boost.
It does this by not injection the fuel till it's required. (Can't detonate if there isn't and fuel in the chamber)
They are cool if you have the deep pockets required to get them running.
