4LT GS Roadster
Chevrolet’s press materials spend a lot of time comparing the first Gen 5 to the current Corvette base engine. But it’s more instructive to contrast it with the first of the Gen IIIs, because it’s easily the biggest thing since. While “99.9%” new, at first glance the LT1 illustration doesn’t look that much different from that of an LS1. Yet important innovations can be picked out, such as DI, VVT, and AFM components - even the splayed nature of the valves can be seen.
