Another thing to note is that Vette's have typically gotten the new technology first, then it trickles down to the cars and trucks a few years later. Since the vast majority of V8's that GM sells are in trucks it makes sense to develop a platform for the vette that will translate over to trucks well. Costly, complicated, higher RPM engines are not what trucks need. LS motors lack low-end grunt as it is in heavy *** trucks.

Maybe what GM could have done is just keep this DOHC motor for the Vette only and then use their LS Series motors for their other line of cars or trucks.
It would have not been because of a performance difference since LS motors make great power for their size but more to distinguish the Vette from the Camaro line and do more experimentation with a DOHC motor in terms of a small displacement, high rpms and FI.
Just saying, it could have been a selling point.

In addition it is less complicated and expensive, the ohv motor. It's not JUST about power, it's about value and durability. Having said that, I think a modern ZR1 with some form of dohc would be great instead of just sticking a blower on an LS. That's what everyone is doing these days, just slapping a blower on and getting huge numbers. Takes some of the fun out of it IMO.

I love the bragging on the LT5 like it was some GM designer that made it. Lotus designed that engine and Mercury Marine built it. When GM tried to do the same, they came up with the epic fail that is the Northstar.

Gm owned lotus then. I guess what you're saying is the ford GT isn't a ford because someone else builds it

Yet you still responded. I'll bite though, what is wrong with the statement? Lets see, did Lotus design the motor? Yep... Did mercury marine build it? Yep. Did the northstar draw design cues from it? Yep. Did the northstar suck? Absofuckinglutely.
Since when did BMW help design the Coyote? Even if it's true, which I doubt, there is a big difference in helping and saying "do what you want with it, just make sure it's 5.7L"
Ford designed the car, it has a Ford designed engine, so it's a Ford. Still it's apples to oranges, we aren't comparing cars here, we are comparing engines. LT5 vs Coyote, so it's Lotus vs Ford, not GM vs ford.
Oh and another fun fact, the best 4 cylinder engine that GM has ever had, was also designed by Lotus. Ecotec. Seems the only thing GM got right in the 80's-2000's was the LS engine.
