    It's easier to list what didn't get E7 heads, every 5.0 or 5.8 engine built after 1987 except for the Lightning and Explorer motors got E7TE heads.

    I guess this leads me to a few more questions if you dont mind:

    1. Were the E7TE/E7TE-PA heads used on Mustang 5.0L after 1993?
    2. What years were the E7TE/E7TE-PA used on the 5.8L (with 1/2 bolt holes)
    3. Any other applications of E7TE/E7TE-PA other that the ones above?

    Thanks again

    Thank you very much! That is very interesting that Ford would not mark or cast-in any other identification other that the bolt holes. It would have thought it would have been very easy for Ford to give the ones for the 5.8L a different casting number - even if the basic casting was the same. So when anyone goes to purchase a set of E7TEs I guess its imperative to check the bolt hole size very carefully.

    Thanks again

    There may have been a part number difference but we'll never know because those numbers aren't found on the parts after they leave the factory. The only difference with the heads found on 5.0 and 5.8 motors is the bolt holes and that difference is accomplished with machining, the raw castings all start out the same, and these heads can even be interchanged afterwords by boring out the holes for a 5.8 install or by using bolts with collars when putting them on a 5.0.

    I am a new user here and see that you have a lot of knowledge of the small block Ford engine. I have a question that I cannot find a definitive answer for. It is my understanding that 'E7TE' heads were used on both 5.0L (302) and 5.8L (351W). However they must be different as the two engines used different sized head bolts (7/16 and 1/2) and the holes in the heads must match the head bolt size. Are there any other differences? How - exactly - are the two heads distinguished by part number/casting number by Ford. Ive seen E7TE heads referred to as simply E7TE but also as E7TE-PA. There must have been some type of pn difference from Ford. Can you shed some light on ths?

    Thank you

    Woop, thanks for clarifying my friend. Your post really put my mind at ease, truly your knowledge outweighs my own. Much obliged Sir. Conanski.

    No.. speedo recal isn't required for gear ratio changes on '92+ trucks. Speed info is obtained from a tone ring mounted on the rear axle ring gear and that doesn't change when gears are changed so your speedo won't change.

    Dear Conanski. I've admired your knowledge for years on late model F150's, but now I have an issue that research hasn't properly addressed. I have a 1995 F150 (OBD1) with a 351W, E04D, and 3.55 Rear gear ratio. In the future, I would wish to put in 4.10 gears, but was unable to find any pure supporting evidence for support on this matter. Putting in 4.10's will obviously change the speedometer output, however, there is a procedure to calibrate said speedometer. Now, if the speedometer is calibrated in this model, will it also change the transmission shift points to compensate for the new gear ratio? I am aware of the calibration calculator used to input the speedometer numbers, but unsure of what it changes exactly. If the speedometer is calibrated, but the transmission shifts differently, a Performance Module would probably be required, or a SpeedCal, but not too many are left.

    Hope to hear from you soon,

    This car would be a good candidate to pull all the parts necessary for a MAF conversion, those parts include the PCM and MAF meter and the complete engine wiring harness(everything back to the PCM), the harness won't just pluf into your truck but you can create something that will from it.

    All 5.0 heads are interchangable but the stock heads on a 5.0HO are no different than what's on your truck. If this motor has aftermarket heads they are definitely an upgrade, if you take these also grab the pushrods and rockers just in case they are different than stock.. for example if the heads have stud mount rockers then all those parts are different since stock Ford heads use pedestal mount rockers.
    Headers are no good to you however the collector location and angle is different than what's on a truck and making them work is more trouble than it's worth.
    Injectors may be useful, your truck has 19lb(yellow or orangish/dirty yellow top), The 5.0HO would have come with the same injectors so if these are a different color they flow a different rate. But you can't just install larger injectors in your truck and expect the computer to adapt, it has to be programmed for them.
