What are the specs of the Ford E7TE heads?

Specifications of Ford E7TE Heads
The Ford E7TE heads were primarily used on trucks and are often referred to as “E7 truck heads.” These heads are known for producing good low-end torque but are considered to be restrictive at higher RPMs. Here are the key specifications of the Ford E7TE heads:
– Valve Sizes: The E7TE heads typically have 1.85″ intake valves and 1.55″ exhaust valves. However, it’s worth checking the valves to see if larger ones have been installed.
– Chamber Size: The combustion chamber size of the E7TE heads ranges between 60.6-63.6 cc.
– Port Volume: The factory port volume of the E7TE heads is 127cc on the intake side and 44cc on the exhaust side, with an average airflow of 125 CFM between 0.100″ and 0.500″ lift.
– Application: The E7TE heads were used on all 5.0L Foxbody Mustangs between the years 1987-1993.
– Performance Potential: When ported and gasket matched, the E7TE heads have the potential to significantly increase power, especially at higher RPMs.
It’s important to note that the E7TE heads are known for their performance limitations, especially at higher engine speeds. However, with proper modifications such as porting and gasket matching, these heads can significantly improve power output, particularly in the mid to high RPM range.
If you have a specific application in mind for these heads, it’s advisable to consider the potential modifications and their impact on the overall performance of the engine.

Why are GT40 heads better?

I personally know tthe GT40P heads make a difference. The biggest difference between the GT40 and the P heads are the combustion chamber and plug location. The P heads have a smaller C.C. than the regulars which bumps comression some but you either need the stock manifolds or special headers to clear the plugs.

How big is the GT40 head combustion chamber?

63-66 cc
GT40 combustion chambers are slightly larger, with volumes ranging from 63-66 cc. The Explorer/Mountaineer heads (GT40P) are somewhat smaller, measured between 58-61cc chamber volume. Thus, GT40P cylinder heads may give a small bump in compression.

What do GT40 heads flow?

A set of brand new, stock GT40P’s will flow 190cfm from . 400 to over . 500 lift intake, peaking at about 195cfm. That’s a serious improvement over stock, and well matched to mild head/cam/intake combinations.

Is porting E7 heads worth it?

Most say, “It isn’t worth it”, and a few seem to think it might be. Well, let me tell you, if you have the time and mechanical aptibility to do so, it will be a rewarding experience. The posted pictures are the before and after dyno pulls of stock heads over ported E7 heads.

How much do E7 heads weigh?

Weight: 152.0 lbs.

What are the specs of the E7TE head?

The iron E7TE heads are far from a performance cylinder head, with small 127cc intake ports, 1.78-inch intake, and 1.46-inch exhaust valves. Our particular set has chambers measuring 61cc, meaning they might have been surfaced at some point, but is still well within the range usually seen from the factory.

Are E7 heads any good?

The E7 head is a great bolt on swap for the older blocks or the replace the E6 heads but if you want real performance save you money and bite the bullet and buy a set of aftermarket aluminum heads. Trust me you’ll be alot happier plus the car will hook better because of all the weight your saving.

How much horsepower do performance heads add?

You could probably expect 30-40 HP just by switching to Vortec or any of the popular after market heads like Dart Iron eagles, Edelbrock Performer RPM, etc.

How do I identify my Ford GT40 head?

How to identify your GT40 heads look for a “GT” or “GT40P” stamp inside the head casting or a three-bar (GT40) or 4 bar (GT40P) stamped on the side of the head. GT40 heads can be found pretty much anywhere you look.
