The 68 GTE 427engine has the same hyd. cam as a 390 GT or 428CJ, the heads have the smaller valves (2.09"I, 1.66"E) the same as a 428 CJ. Other than .100" more bore, and .200" less stroke than the 428, the 68 427 is equipped almost identically to the 428CJ, but with a higher HP rating, and no cold air offered.
Also, there were later GTEs made with the 428CJ replacing the 427 mid year, and those 428 cars did have cold air scoops. The 428 is a better combo IMO.

Rory,
The 427 engines used an exhaust manifold that looked like the 390 engine. The 428CJ manifolds were far better.
