The GM 6.2L Gen 5 LT1 small-block engine is one of the most technologically advanced engines in the world and completely changes the game. ... The LT1 intake manifold, ...

And based on their findings through millions of simulation hours of computational fluid dynamics testing , the valves are held at new, 12.5-degree intake/12-degree exhaust angles, vs. the Gen 4 ...

Like the 1997 LS1, the Gen 5 LT1 features aluminum-block construction, 6-bolt main caps, and a composite intake manifold. The LT1 even shares the same 4.065-inch bore, 3.622-inch stroke, and 376 ...

ProCharger and Scoggin Dickey Parts Center tested a new low-profile air-to-water intercooler intake manifold for LT engines. The setup, capable of over 1,344 hp, was tested on a 402-ci stroker engine.

Without the LT1’s distinctive front-breather intake manifold, the engine resembles a standard small-block Chevy, but there are still lots of LT1 uniqueness hidden inside. See All 22 Photos 2.

With the engine behind the driver, engineers were less concerned with forward sightlines and free to make the LT2 taller than the LT1. A new intake manifold with equal-length runners is mounted so ...

The new LT1 used a new block, intake manifold, and cylinder heads along with a “reverse cooling” system, but the basic design, including engine mounts, bolt patterns, bore spacing, and the 5 ...
