The C8 generation Corvette came out in 2020 and the aftermarket has run into road block after road block with modifying its 6.2-liter LT2 engine. From GM’s Global B PCM architecture keeping performance shops from tuning the engine to internal upgrades for the DCT transmission so it could handle more power. While these hurdles were overcome after some time, one thing that has kept engine builders from building short blocks and crate engines is the availability of the LT2 block.

GM’s Chevrolet Performance division has always offered parts for its performance V8 production engines, from bare blocks to cylinder heads to internal components. This allowed the aftermarket and race shops to build short block assemblies and crate engines for customers using brand-new parts instead of used pieces. GM has not offered the LT2 block over the counter at your local dealership parts department and has not seen a need to let its Chevrolet Performance division offer the C8-specific 6.2-liter LT2 block to the public either, until now.

In the past, Chevrolet Performance announced their latest and greatest products being released for the upcoming year at the annual SEMA show in Las Vegas, but since they no longer attend SEMA, their latest releases have been left mostly silent. In the latest 2025 Chevrolet Performance catalog, they snuck in a new part number (19436362) for an LT2 engine block. They have not made any press releases about their latest offering or even provided the public photos.

It’s no surprise GM held back releasing the block. They didn’t think customers were going to be doing custom engine builds with their Stingrays, but time has proven them wrong. If you think you could use one of the LT1/L86 blocks in its place, think again. The LT2 block is specific to the C8 platform and not interchangeable.

Snuck into the 2025 Chevrolet performance catalog on page 88 is the new-to-the-public C8-specific LT2 engine block.

For starters, the engine mounting bolt pattern on the sides of the block is different between the LT2 block and the 6.2-liter block offered in the trucks, the 6th generation Camaro, and the C7 Corvette. The bell housing bolt pattern on the back of the block is different for the DCT transmission. While the other Gen-V LT blocks share a bell housing bolt pattern very similar to the LS family, enough to make transmission swaps simple, the bolt pattern for the LT2 is not similar enough to make them interchangeable.

A cutaway on the LT2 engine shows the dual-chain setup to run the valley scavenge pump off of the VVT actuator.

The biggest difference of all is the multistage dry-sump oil system and the provisions for the scavenge pump in the valley and timing chain areas of the engine block. Above the camshaft on the LT2 block is an opening for the valley scavenge pump that is not present on the other LT engine blocks, and there is no room to machine the other blocks for the provision either. The LT2 engine block is also cast from a stronger A319-T7 aluminum alloy that is stronger than the other production aluminum blocks.

Instead of C8 Stingray owners having to supply engine builders and race shops their own LT2s to make a custom engine built for boost or a stroker, now you can have a short block or crate engine built from a brand new LT2 block. An official MSRP has not been released just yet, but our sources estimate it will cost less than $3,000 when part number 19436362 hits Chevrolet Performance Parts dealers.
