From Hagerty below but I want to know is why the exhaust is as shown in the pic? Similarly the spark plug location.
General Motors’ sixth generation Small Block V-8 will arrive for the 2027 model year in two sizes, reckon the folks at GM Authority.
The new motor is set to make its debut in the 2027 Chevrolet Silverado 1500 truck but, as with the Gen-V engine, it will find a home across the range. That could include the firm’s upcoming rear-drive sedans, as well as the C8 Corvette.
GM Authority says that its “sources familiar with the matter” revealed that the Gen-VI small block will likely be offered in two capacities. A displacement of 5.7 liters will be the entry point, with a 6.6-liter motor as a flagship. The current small block comes in five flavors: The 5.3-liter L84, 6.2-liter L87 and LT2, 6.6-liter L8T, and a supercharged 6.2-liter LT4.
According to the report, the next-generation engine will make incremental improvements in efficiency without a dramatic overhaul in its engineering. GM President Mark Reuss has promised a four-to-six percent improvement over the latest models and a 10 to 12 percent uptick compared to when the Gen V small Block was introduced in 2019.
GM Authority believes that the Gen VI V-8 will stick with its 90-degree vee and pushrod setup, but when pressed, GM itself would only confirm that the small block will live on. “GM has shared that there will be a sixth-generation Small Block line of engines. No product details have been shared. We can’t comment on speculation,” said a GM spokesperson.
