GM's Disinformation Campaign Now Reports the LT7 Motor is a 4.3L Diesel

While everyone is arguing about the size of the upcoming LT7, what if I was to tell you it’s now going to be a 4.3L V6 diesel engine? Don’t shoot the messenger…I’ve got sources! According to the latest update of the GM parts catalog, that’s what it shows.

It’s sometimes funny to watch how General Motors reacts after they get caught with their fly down, or more specifically, when future products show up in public. Almost a year ago, it was the E-Ray visualizer which was leaked to the public and with screen captures going live almost immediately, they had no choice but to acknowledge that the new E-Ray was coming, saying “Looks like the holidays came early for a few astute Corvette fans. Stay tuned for more” in a statement provided to us at the time.

More recently, we learned through the GM Parts Catalog some key information for the upcoming Corvette ZR1. In that leak, specific components of the expected LT7 appeared to confirm the motor was a 5.5L twin-turbo with AFM and VVT. Once the word got out on that, the parts catalog was scrubbed later that day and those part numbers were removed.

But then something funny happened…or should I say funny-business?

On the Corvette Forum, member “JMP” who is credited with the original leak came back with another “bombshell” as he says “GM disinformation has started lol” and he shows this screenshot of a dropdown list on Corvette motors, and now LT7 is classified as a 4.3L V6 diesel!

According to JMP, the LT7 rpo code was used previously in the 1980s where it was indeed a 4.3L V6 diesel.

Another CF member named “mfain” thinks that “packaging the LT7 in the ZR1 is going to be tough, and it probably won’t help the overweight situation,” referencing the fact that the 4.3L diesel engine was GM’s “biggest and heaviest powerplant to be fitted into the Oldsmobile’s front drive A-body.”

CF member “UniqueDoug” sums up our feelings on the issue, saying “Is this a controlled leak from the last uncontrolled leak? I can’t keep up lol.”

Neither can we, lol.

  2. GM doesn’t realize that the Corvette community is not stupid like the millions of Americans that swallow the government propaganda from the controlled main stream media.

  6. In 1982, dad purchased (for my mom to drive) a Buick Century Limited with the 4.3 diesel. My god, what an engine! Not a lot of horsepower, but what torque. Loud and clattery at startup and low speeds, but at interstate speeds – so quiet. 30 mpg just running around town, and 38 mpg on long road trips. Never had any issues with it but for its first winter when it dropped to 12°-15° for a couple of nights, the diesel fuel gelled, and the engine wouldn’t do anything but idle. We put a couple of ceramic space heaters in the (unheated) garage that third day, and by that evening, it was running fine. I started doing what the VW owner’s manual recommended (at the time) for below 32° ambient temps for my Rabbit diesel – when filling up with diesel fuel, first pump in 1 gallon of regular unleaded gasoline for every 10 gallons of diesel, and that kept the fuel from gelling. Car ran great every winter from then on, for 5 years until dad traded it for a 1986 Century Limited with the 3.8 V6 (gas – an another great engine!).
