It seems like it would be a great fit, especially with turbos providing better low end torque and the 8 speed transmissions better at keeping them in the power band.

The Denali and ZR2 need some sort of flagship engine anyway and the 3.6TT is a good choice with its easy git in place of the standard 3.6. Even if they could find a way to mount a small block, it might be a good idea to further differentiate from the Silverado and Sierra in engine options.


Maybe though, they don’t want to do it as a way to keep themselves different from EcoBoost.
