I don't know. I don't for them that closely. I knew they had them. I'll have to check. Kind of a scary thought if they did, there has to be a reason.
Z06 Flat plane crank?

My info is that Ford is dropping the gt 350. They had plenty of problems with that engine due to
the crank. I’m pretty sure with the higher rpm that they run at maintenance is going to be a concern.
they are running them in the race cars so that’s a good sign. Jmho

Ferrari costs have nothing to do with them having a FPC engine. Ferrari engines rarely if ever break. Parts and labor for any exotic car have a HUGE bend over cost e.g. yearly routine service 1-2K. Sky is the limit if there is an issue.

Yeah I get that. I guess I was referring to the increased need of frequent service due to the much higher rpm the engines would be spinning. It’s outta my wheelhouse...that’s why I’m asking.

they added so much metal back to the crank to fight nvh problems that it wasn't much lighter
like our old lt5s, they puked oil above 8k which folks love to hit
I'll say this, they do sound awesome at the track
if you are a mustang fan, the new shelby would be a better bet
nice round 750 with a dct costs a bit more than the c8, but a worthy track car finally

What will be costly is all the sales GM is going to lose if they go with an NA FPC making about 600/475 instead of a TT setup making 675/675.. A lot of folks, like me, want no part of a high strung/high maintenance race motor that's way down on power from it's C7 counterpart and is going to go for a $30k premium over a Stingray. GM sold about 5k C7 Zs a year, GM will be lucky to sell half this amount with a small displacement, low torque, NA FPC. With every other manufacturer moving away from FPCs and NA, I have a hard time believing GM is stupid enough not to know this. For these, and many other reasons, I think the NA FPC is a head fake and that GM will go with a TT setup, but that's just my opinion and only time will tell.

Yes, Ford dropped the flat-plain-crank from the GT350 Mustang citing reliability issues. I definitely think there will be more maintenance and costs associated in maintaining the Z06 variant.

lots of manufacturers are embracing the flat plane crank. most are in the 3.8 to 4.0 size and use some pretty exotic rotating parts to make it work
ford used quality parts, but the big displacement is harder to tame with a larger stroke Once gm makes a dohc tt vette, I'm in.

Ford never stated that they stopped using the FPC because of reliability issues. The GT350 is the longest running of their special editions, running 6 years. Have their been engine failures? Yes, Has the C8 had engine failures? Yes. Is either case relevant? Maybe. I have a 2019 GT350R. It has the gen 2 engine which was revised primarily to be common with the GT500 Block. Stronger in a few ways, better bay-to-bay breathing help control crank case pressurization oiling issues. Some of you may recall, early LS1s had that problem(My wife's 97 spun a rod bearing at the track). It takes 10w60 oil and runs 100psi+ oil pressure.
The GT500 can be had for 73K up. Without the Carbon Track pack seems like pretty good value.

Don't worry you will be able to buy a TT C8. It just wont be a Z06. Sounds like your best bet for what your looking for would be to boost a C8 stingray.

it doesn’t have big enough bore centers to get to 5.5 liters and have high rpm. They have the tooling, they are using the block and heads in the C8R.

Are you saying it has to be 5.5, because of the racing rules for the c8r. Stating that there needs to be x amount of 5.5l production c8's. Therefor the z06 has to be 5.5.
