Cadillac Blackwing V8 Engine Still Available Via GM Parts Catalog

The twin-turbocharged 4.2L Blackwing V8 engine was only ever offered in the Cadillac CT6 Platinum, and Cadillac CT6-V, of which only 1,500 examples were ever produced. That makes this eight-cylinder motor one of the least common modern GM powerplants, which is why we were so surprised to see complete Blackwing engines being offered for sale via the online Cadillac parts catalog this week.

The Blackwing engine is listed on the Cadillac parts website as a ‘GM Genuine Parts 4.2L Gasoline Engine’ and carries the part number 12662913. Cadillac is charging $21,666.67 for the engine before tax, plus a $3,500 core charge.

To be clear, this engine is being sold as a service replacement part and is not being offered via the automaker’s performance parts catalog as a crate engine. So while it’s technically possible to purchase the twin-turbo LTA V8 and drop it in a restomod or another classic car build, it’s mainly listed in the parts catalog in case any Cadillac CT6-V owners need an engine replacement. Cadillac says it’s not building any more Blackwing engines, so once this lot is sold out, that will be the end of the road for the twin-turbo DOHC V8.

To purchase this engine, customers will first have to call their local Cadillac dealer and tell them the part number. The motor will likely arrive at the dealership on a wood pallet, and seeing as it weighs in at 518.64 pounds, the buyer will likely need a large SUV or pickup truck to haul it away.

The Cadillac Blackwing V8 engine was standard in the 2019 and 2020 model year Cadillac CT6-V and optional in the CT6 Platinum. The engine produced 550 horsepower and 640 pound-feet of torque in the CT6-V and 500 horsepower and 574 pound-feet of torque in the CT6 Platinum. The motor features dual overhead camshafts, an aluminum cylinder block, a forged steel crankshaft, forged steel connecting rods and aluminum pistons.

GM fans who are willing to drop some cash on this rare piece of GM engineering history can start the purchasing process via this link.

  1. It’s cool that you can buy these engines without the car. I’d transplant it into a custom lifted 1995 Toyota Truck.

    1. Sorry sir, you’ve been added to the “do not sell to” list

  2. Dumb Dumb Dumb. Finally get something right and then cancel it. This Engine should have been available in the CT6 from the start.

    1. It definitely should have been continued in some other vehicle. As cost-conscious as GM is, you’d think they’d want to make up their development costs instead of discontinuing it after two years.

  3. Looking out for some one to do a CT5-V PURE Blackwing mod,

    1. You’d have to use a 2020-2021, since 2022+ can’t do it road legal per EPA rules. Engine must be same model year or newer.

  4. Just a warning for those in California (and possibly other CARB states), you can’t use a crate motor. Has to be pulled from a car with a VIN. And yes, the CA inspector signing off on the engine change will want the VIN and paperwork proving it.

    Ask the Solstice folks in California that bought crate LS2/LS3’s and had to sell their cars out of state.

    1. Oh, and I almost forgot, the donor car has to have a CARB certification on it. Even if it’s virtually identical, without the VIN plate from the donor car having CA emissions approval (“50 state legal”) they’ll deny for that too.

  5. A FEW STATES IN THIS COUNTRY, THAT DON’T CARE WHAT YOUR RULES ARE IN CALIF.

    1. I can proudly say Michigan is one of those states, we don’t even have sniffer tests here. It would seem that the only thing they care about is whether or not your exhaust is too loud (which it seems like that doesn’t even apply to Harley’s).
