Is the VIN format known for the Camaro yet? Are those vehicle IDs partial VINs?

Someone mentioned in the other thread the vin doesn't match a ZO6 but that would make sense to me.

There's nothing with a 6G VIN in the GM North America lineup right now.

Also, there's a vehicle listed with an LT1 and an M5U transmission. LT1 is Corvette/Camaro's V8. M5U is the 8L90 Hydra-Matic for trucks. That makes zero sense.

Edit: Never mind, M5U is used for cars as well.

Edit #2: Never mind, 6G is GM Holden-sourced vehicles.

Car #2 is a 2015 1LE, looks like #1/3 are 2016 1SS models.

I'm guessing #5/7/8 are Corvette Stingrays, #6 is a 5th gen SS automatic, and #9 is a Z06. #10 is one of the HD trucks.

Yeah doesn't tell us anything. The 1LE's listed ID doesn't match a 2015 VIN format.

Also: MVB-NS = Manufacturing Validation Build - Non-saleable. MVB-S = Manufacturing Validation Build - Saleable.

I really hope that if they make an LT4 Camaro that they do not try to make a Z/28 out of it....

I thinking they will some how combine the ZL1 and Z28 together like they did with the Z06. We will see

I am getting the same feeling since they did that with the Z06 (and honestly they really just made a faster ZR1). I hope that they don't....

I have a plan B for them, take the 6.2L LT1 engine and give it the same treatment that the LS7 got (titanium rotating mass and all). With the shorter stroke move the redline up to 7,500-8,000rpms. Then give it the 305s on all corners DSSV shocks ceramic brakes etc.... like the last Z/28 and boom....

Or you can make a standard Z/28 without the DSSV and ceramic brakes and R rubber and offer a Z/28 R package for a few thousand dollars to add that stuff on.

LT1 still has growing room..... raise compression,cam, add dry sump, there's your Z/28 motivation.

It's already forged bottom end with (only) 11.5 compression...

Emissions.

One of the reasons companies go with forced induction is it's easier to hit emissions targets with that rather than N/A.

Ford had "harder than normal" times getting the 5.2 FPC motor to pass, and that was after the 5.8 Trinity motor at 662 HP.

Well God bless CAFE

Personally, I like torque, maybe a cam, intake and HD valvetrain, I'd hate to see the torque drop with a destroked crank.

300 lb ft @ 1000 rpm is pretty awesome!

If you saw what it takes to make a reliable pushrod valve train with 8k RPM shift points you would see that a LTx production engine that revs that high is very unlikely. Now a 427ci production version of the LT1 with around 7k RPM shift points and 550HP/TQ is totally doable. A engine doesn't have to rev high to make a lot of power. Ford is forced to rev their engines high to make power because of the lack of displacement. I would rather have high displacement and more torque with the same amount of power vs less torque and more RPM any day.

The LS7 valvetrain was rated for 8,000+rpm operation....

I like the idea of having a diverse offerings of engines, I like the idea of having a Camaro with a supercharged 640BHP LT4 engine (ZL1). However I just think it would be cool to see a 6.2L 8,000rpm N/A engine in a Z/28 to compete with the Mustang GT350.
