The GT is getting basically the same motor as the coyote. Well the Roadrunner actually. The engine for the GT I am old will have as cast ports that are very similar to the CNC port the boss heads had. The engine will also have larger valves, larger intake cam and IMRC plates.
So if the GT motor is like the old Boss motor what will the GT350 / GT350R have? More displacement, larger cams or what else? I am excited to find out!
