The C7 Z06 had major overheating problems. The team behind the new LT6 V-8 worked hard to vanquish these issues.
Recently, GM hosted an event where engineers from the Chevrolet Corvette and Small Block programs gave a three-plus-hour presentation on the LT6, the engine powering the new C8 Corvette Z06. The most common point of reference throughout was the LT4, the supercharged 6.2-liter V-8 used in the C7 Corvette Z06, and currently found in the Camaro ZL1 and Cadillac CT5-V Blackwing. It's a killer engine, though early on, it was plagued with faults.
Chevy went fancy with the engine materials, for both strength and lightweighting. The forged titanium rods are the lightest ever in a Z06, as are the forged aluminum pistons. The pistons and mechanical finger followers get a diamond-like carbon coating to reduce friction. With no hydraulic tappets, the finger-follower valvetrain has “set for life” lash and gap, and after 100,000-mile tests, engineers saw "negligible" wear on these components. They also claimed to see no unusual oil consumption in track testing, and said the vacuum created by the new crankcase design actually helps keep the piston rings seated.

Corvette Engineers Bought A Ferrari V8 To Help Develop Z06
GM who?
You mean Mary’s soon-to-be-bankrupt-again clown show?
The one that makes Cadillacs in China for sale in America?
The maker of the China-built-engine-powered Envoy?
hahhaahahaahhahah
They have nothing I want.
Eff em and their ‘Vettes.
In an incredible, stupid move, GM quit printing brochures for its models...
You must go on line and “build what you want.”
GM hasn’t made a good car since the 1960’s .
Just Damn!
.
Eeeewwwww,
We had a Good Run.
Anther internal combustion destined for the scrap heap when there’s no fuel to combust.
At least they finally joined the flat plane crank party in the US after Ford did.
I’m about to tear into my 75 C3 350 SBC on Monday with an Edelbrock Performer EPS intake and Edelbrock AVS2 carb update.
I just want it to start every time !!
Mostly agree with a few exceptions; 1970-72 Pontiac GTOs, Olds 442s, and Buick GSs and a few other rare ones like the 1979 Trans Am, and the mid-1980s Buick Grand Nationals, Olds 442s and Hurst Olds.
A car won't get me home anyway so GMC 4X4 is my choice.
I look forward to when I am cleared and up to fooling with my old K5 and the Jeeps.
Next month sometime. When I am deemed ready for surgery.
I’ve been out of the game for awhile. I was not aware of this motor.
Thanks for posting (and the non-paywall link)!
When will they cease production?
When the government pays or taxes them to do so.
This,1963 Corvette was the last attractive Corvette made.
That’s not a 63.
The C7 Z06 had major overheating problems..
Then why did they put it on the market? Typical GM.
Thousands...millions of miles of development. Millions on man hours of engineering. And they put an engine, in a performance car, with “major overheating problems”. Typical
