Literally as we type this, Chevrolet is rolling out the newest version of the venerable small block. Dubbed the LT1, this engine displaces 6.2L, will make 450hp in the Corvette, has the cam in the block, uses pushrods, active fuel management, variable valve timing, an 11.5:1 compression ratio and an aluminum block with iron liners. The whole weight of the package is listed as 465lbs ad the torque output matches the horsepower at 450 lb/ft in stock form. The factory rev limiter is said to be set at 6,600RPM. Connecting rods are forged powdered metal pieces and the firing order is - 1, 8, 7, 2, 6, 5, 4, 3.
We’ll have more info in the coming days but this at least gives you something to chew on. Scroll down to see the GM press photos of the engine!
