Essentially, you can port your E7TE heads, which will earn you about thirty horsepower, or you can upgrade to GT40 heads, which will also earn you about thirty horsepower.

GT40 vs GT40P, which are better? Really, when you get down to it, neither head is any measurable difference better than the other. The GT40P does have a slight edge over the GT40 cylinder head because of its smaller chamber volume. The smaller combustion chamber can net a bit more compression, but only marginally.

How to Get the Most Horsepower Out of a Ford 302

1. Install a performance aftermarket cold air intake to replace the Ford 302 factory air intake.
2. Install a performance aftermarket exhaust system to replace the Ford 302 factory exhaust system.
3. Install a forced induction — supercharger or turbocharger — kit.

Standard Ford 289 and 302 small-blocks were factory-rated between 200 and 230 hp. The vaunted 289 High-Performance engine was said to make 271 hp. Today, if a 302 Ford makes 360 hp on pump gas with a hydraulic cam, most experts consider it to be a pretty good motor-at least until Joe Sherman steps up to the plate.

This intake came about because it is said that it took too long to produce the tubular intake and was too expensive. So, Ford made a cast version that rivaled the performance of the of the tubular intake, but wasn’t as visually appealing. This was featured on the 93’ Cobra and Cobra R Fox.

They also installed GT-40-type cast-iron cylinder heads, the tubular “tuned” manifold, tubular stainless-steel headers, larger intake (1.84-inch) and exhaust valves (1.54-inch), high-flow ports, high-rate capacity fuel pump, and injectors, revised combustion chambers, a redesigned air filter for improved airflow and a true dual exhaust system.

With the GT40 intake you are sure to add increase performance to your stock intake on your Fox Body and we hope this article gave you more insight on the different options you can get. Also view our other article explaining what GT40 head are!
