Lt1 intake manifold6/7/2023 ![]() ![]() In the end, the Gen 5 LT1 engine will have accumulated an equivalent of over 1.5 million miles of validation testing. The spark plug was also moved closer to the center of the combustion chamber, helping push the flame for the combustion process closer to the center of the cylinder, increasing the direct injection system's efficiency. ![]() Large, 2.13-inch hollow intake valves breathe in fresh air while 1.59-inch hollow sodium exhaust valves help expend the consumed mixture. The change, along with an entirely new intake manifold design, enables a straighter path for the air charge into the combustion chamber. Edelbrock LT1 RPM Air-Gap Intake Manifold Kit 1994-97 LT1 52MM Twin Throttle Body Satin Finish View Details 1,485.07 Estimated to ship direct from manufacturer on 05/30/23, pending manufacturer availability. The new Holley EFI Hi-Ram intake provides the ultimate performance with the new GM direct injected Gen V 6.2L LT1 engine. The reversal of the position of the valves in the head is another significant, while not outright noticeable, change in the Gen 5 small-block. Together, they work to exploit the high compression, mixed motion parameters enabled by direct injection. The resulting cylinder head is brand new, along with a special, dished piston. More than 75 iterations of the combustion system alone were developed and evaluated before the final design was selected. That's the equivalent of 18 billion typed pages or 23,000 DVDs. Using GM's Powertrain Development Center, a sprawling 450,000-square-foot facility among the most technically advanced powertrain development centers in the world, the computational analysis alone that went into the LT1's development took five years and consumed 0.1 quadrillion bytes of disk space. Posted about my SAB listing a few weeks ago about not showing up in search only when you entered the exact name. The Edelbrock Performer RPM Air-Gap LT1/LT4 intake manifolds are manufactured from aluminum and feature a natural finish. One of the most technologically advanced engines in the world, the LT1 also represents the most significant redesign of the small-block ever.
