The truck description says complete 6.0 drivetrain. Uh, yeah, 6.0. That's why the bad guys took everything but the drivetrain.
As for the hot rod, I think that's what Logano had under the hood of his Ford. Seems the Chevys and Toys had a little trouble catching him. BK had the same set-up in the #2, only he mistakenly hit the after-burner button, which created lots of fire and smoke.
