Post GM planning L88 Corvette Stingray C7? Files trademarks to revive L88 engine code

Is GM cooking up something designated L88 for the C7 Corvette Stingray?!

The automaker filed two trademark applications for the L88 name. The first was filed on August 4, 2012 for “exterior and interior badges for motor land vehicles”, while the second was filed on September 18, 2012 for “decals”. The trademarks were then published for opposition in October of 2012 and subsequently approved to the USPTO principal register on January 15, 2013.

The General used the L88 designation in a very select amount of Chevrolet Corvettes from the late 1960′s, of which currently go for over $500,000 at auctions. Essentially, it was a racing engine that could be directly ordered from GM from the factory that boasted 427-cubic-inches (7.0-liters), and is often hailed as the ultimate Corvette engine that’s ever been made to date.

Specifically, it was a modified big block with lighter heads and bigger ports, a more aggressive camshaft, aluminum radiator, smaller flywheel, and a massive Holley four-barrel carburetor. Oh, and an absolutely crazy 12.5:1 compression ratio. Again, we’re talking about an engine that was from over 40 years ago. This sky-high compression was achieved through 103-octane racing fuel, and was officially rated at 430 horsepower, though claims as high as 560 horsepower have been made.

In addition, the engine order also called for several modifications to the Corvette. These include a more rigid suspension, a limited-slip differential, and even heater and radio deletions. As street legal as these Corvettes were, it was clear their purpose was for the track. This was the grand finale for the Chevrolet Corvette C2 in 1967, before the C3 launched in 1968.

Only 20 buyers were hard-core enough to order such an engine. This also explains their value. Now, we don’t see The General to release an engine with a 103-octane tune, but damn, anything that would carry the L88 name would certainly have to live up to the pedigree in one way or another. And we certainly hope this trademark filing isn’t for housekeeping. Please, GM. Please just shut everybody up, and just build a successor to the L88.

Not trying to be a buzzkill, but it's probably just a renewal.
Similar to how Z28 was renewed last year.

I've heard about the term LT4 being used for a C7 engine too.

C4 engine nomenclature again?

The old LT4's were 5.7 litres. The principle reason it was developed was to give an 10% increase in power over the LT1 until the LS1 was released with the C5 gen.
So you think GM might do the same with the 5th gen LT1 to offer with the next Zxx? From what I've read, they added different heads and intake manifold and changed a few items on the bottom end on the old LT1's to make it an LT4.

LS3 got an overhaul and is now the LT1.

Could the LS7 get a similar overhaul for a Stingray Z06 and be designated the L88?

I think there is a high possibility.

I'll hold off and wait and see if they do anything with the Z/28 stuff from a year or so ago. It could be a marketing plan to keep aftermarket companies from producing badges and cutting them out of the licensing fees.

I think that the L88 will definitely be a 427 HO V8 for the C7 and not just a means to keep these old engine designations from being snapped up by the aftermarket. GM is also using L83 for the 5.3 and L86 for the 6.2 2014 V8 truck engines, so it makes perfect sense to apply L88 for the LS7 replacement in the C7.
