After numerous searches I am still at zero. I am trying to find out what the difference is between my 6.2 L86 2018 Silverado engine and the same year Corvette engine that lists identical specs, but puts out considerably more power. Is just in the cam specs, or in the exhaust, or the throttle body? The LT2 Corvette now makes 496 HP and 470 ft lbs or torque. I know LT2 has revised intake runners (all the same length), a revised AF sensor, low restriction exhaust, dry sump lubrication, and a revised cam. It is still basically a LT1 engine that gained 75 HP and 10 ft lbs of torque, an 18% power gain. The LT1 Corvette engine had 40 more HP than My L86. What made the additional horse power. Can anyone shed some light? Thanks.
