This thread totally turned out badly. It seems every time someone mentions an impressive V8, it always has to end this way. Lame.
Can't anyone just appreciate the aspects of this engine
as well as 4-cylinders? It's not a war. Reliability has little to do with it either. Reliability often has little to do with the layout or tune of the engine. Toyota Supras can honestly sometime produce 1000hp reliablly, wheras a lot of older Jags with more displacement and less power can't drive a block without breaking down.
This engine produces masses of torque, weighs very little especially for it's displacement, and is remarkably efficient for its output. It's not trying to replace 4-cylinder turbo engines, so what's the big deal? It's almost as if nobody is capable of simultaneously appreciating the LS7 and something like the FQ-400's Turbo 4.
I hate to try to argue with you, because I know I'll just end up with 12 pages of text in reply
Just keep in mind what we're looking at here. Of course the LG mods are not covered by the factory warranty. Then again, the 600hp inline-4 previously mentioned would not be either. We do know that in stock form the engine is reliable and gets excellent efficiency-per-output (I am hesitant to say it has "great milage", because nothing with this much power gets "great milage"). The LG modifications (the largest gain came from headers) generally do not increase power disproportionately to the decrease of efficiency. Testing so far (again, in stock form) has shown no reason to doubt it's just as reliable as the LS1 or LS2. I'm not saying you're wrong about asking any of these questions, just that both of you have gone a little off-track. Again, let's make sure this isn't a "battle of the engines" - both types offer advantages over the other. Maybe not so much earlier, but if you read Juggs' most recent post, it's not hard to see that he's being totally reasonable.
