because it's confusing and unnesessary. It's not hard to come up with something that hasn't been used already. SR Series. JQ Series. XA Series. See? Easy.
In 3 years when some of these things are out on the market, I don't want to have to dig through 400 Craigslist postings to find the "correct" LT1

I already have a hard enough time explaining why my LM7 isn't a "tree fiddy."

I've been waiting on this, I see a lot of hot rod potential. 
...as for the prior comment on unfriendly computers... Gen III computers used to be awe inspiring un-tunable magic boxes - until someone hacked one. Now everyone has a copy of HP Tuners or EFI Live.
Put simply, just after the first fence or wall was built a creative fellow invented the ladder. It's only a matter of time.

Yeah? And what about the guys on message boards like this asking "LT1 to LS1 fuel lines?" Now everyone has to clarify everything over and over, and it's totally unnessesary. And I stated in the very first post that there were already LS engines decades ago....doesn't make the idea to name this series LT any less stupid.

If it follows along with the LT series reputation then it shouldn't be around too long lol. I don't see this heap of over-engineering being any better than the Ls. They should have just updated the Ls series again. This new design looks overly complicated for no real reason or benefit. Now we have to take the entire top of the engine off to change an injector? And now the injector will be triple the price!
I really hope this thing is really awesome, powerful, and reliable for at least 200k miles, or else it wouldn't be worth dropping the Ls.

a lot of people seem scared of new tech.
im pretty excited about this. its still a cam in block pushrod motor, but has some great new tech mixed in.
whats not to love? again back to my bmw history, aside from early on issues which i doubt this motor will have, the direct injection did wonder for efficiency and performance.

It seems to work good for me. Gets 20-22 MPG in the highway too. Although, yes, I wouldn't mind a good EFI setup. The whole cold starting thing is a royal pain in the can. I'm with you in thinking anyone who carbs an engine like the future LT1 has to be smoking some serious weed.

Seems pretty simple really. They basically moved the fuel rail and injectors under the intake and put the injectors through the head into the combustion chamber. Then worked their magic on the rest of the design.

the water pump is weird and the belt tensioner looks like they bought it from bmw.
If direct injection is scaring people, I'd steer away from diesels. They've somehow been doing it for... ohh 80+ years. At least the L-tee engine family still has pushrods. I'm pretty sure the entire hot rodding community's heads would literally explode if the General moved toward DI and OHC at the same time. I personally can't wait to shoehorn one in the Nova.

Its great and all that they made this new engine. But what they really needed to do was make a smaller diesel to go into the avalanche, half ton silverado, tahoe, and suburban! How long are they going to let those trucks get crappy mileage with no option for a diesel engine!? Come on GM!

450HP with a 200* cam with a 50lb.ft. torque gain. Amazing. These raised intake ports, almost into the valve covers, bleed HP. In typical Chevrolet launch mode we get the basic release and in 3 years we'll see 600+HP with a cam swap and headers! I'm an all motor fan so power adders don't mean ? to me. I'd like to see some flow numbers with these smaller 2.130 intake valves, although they are canted 2.5 degrees.
