Default Re: new doch 32 valve vette engine on its way

Forgive me for being unclear. My point was only that the three letters "LT5" is currently unique for the Corvette C4 ZR-1, and pretty much the only thing unique one could use to identify it. Googling LT5 now, gives a wealth of information regarding these vehicles, but if the next gen. Z were to use the same lettering, this would change quite rapidly. Similar to doing a ZR-1 search these days. What's relevant for our cars become diluted in the masses of information regarding the new car(s).

LT5 is licensed by GM they can do anything they want with it.
I love my car and GM can not devalue it in any way!

They can use ZR-1 (with or without the -) and LT5 all they want.
There's only one...!
(the C3 & 6 weren't too bad though, even
though they had only one cam...)
If "they" don't get it", it's their loss!

At the end of the day, LT5 and ZR1 is whatever GM wants it to be and there really isn't anything we can do about it. From the sound of things however, there are still people in the Corvette group that have a soft spot for our cars. And as we had hoped, it looks like they are retaining the LT5 designation for a DOHC v8.
And that means more people are going to be interested in the legacy of that motor.

Not a chance at 6.2L and subject to production durability and nvh requirements.

Flat plane cranks are best reserved for sub 3.5" stroke.

Todd,

The 5.2L Voodoo is a 3.6496"(92.7mm) stroke. I think Sam here is running a flat plane in a 385. I'm just speculating.
