Although the 428 is about the same displacement as the 427, it had a smaller bore (4.135" vs 4.23") and a larger stroke (3.78" vs 3.98") due to efforts to decrease production costs. As a result, the 428 was less rev-happy but it gained a low-end torque punch that was absent in the 427.

Like Tasca's original creation, the Cobra Jet mixed police interceptor parts with bespoke Ford performance gear to build on the 428's already-impressive performance. Featuring a compression ratio of 10.6:1, the 428 CJ made use of 427 cylinder heads, upgraded connecting rods, and an iron intake manifold matched with a Holley carburetor.
