    Engine firing order isn't a problem when it comes to the injectors because they are wired the same for both engines. The problem with using a different harness is matching all the inputs to the correct wires at the junction connectors going back to the computer. The only way to do that is by comparing wiring diagrams for the two if you can find them.. the generic diagrams you find in a Haynes manual are no good you need authentic Ford diagrams for each year and engine, or by buzzing all the wires in both sections and making a list to ID them, and then swap wires around where necessary in the block connectors so that everything matches up.

    I have read many of your posts about swapping a 351 for a 302. Your first recommendation seems to be use the 302 wiring harness. Unfortunately, I read them too late. What can I do if I don't have the original wiring harness?

    I have a 1993 F150 extended cab 4x4 with an E4OD. The 302 blew, and a friend said that he had a 1994 351 that I could have. He would even help put it in because he has done several 302 to 351 swaps. Unfortunately, his swaps were 302 HO to 35, which can apparently use the donor wiring harness. We took the 302 out and recycled it with the original wiring harness.

    I have been looking for another wiring harness for about a year now with no luck. Is there another option? Can I rewire the 351 harness? I will appreciate any suggestions that you have.

    Thanks very much,

    Best place to put the O2 is in the passenger side header collector, don't worry it doesn't need to see both banks to work correctly.

    I built my exhaust 1 piece at a time, mounted the headers with a couple bolts and located the O2 sensor where it would interfere with something, remove that header and weld in the bung. Then put it back on, bolt on the flange adapters and fit the first sections of pipe, mark or tack them in place, unbolt those pieces from the headers and finish the welding on the ground. It took me a whole day to complete the job as you might expect but it fit nice and flowed much better than a crimped job from the muffler shop.

    Hey man got a couple questions for ya. I saw a post of yours talking about a 2 into one custom fabbed exhaust setup you did. http://www.ford-trucks.com/forums/12...exhausted.html

    My truck is a 90 f-250, 5 speed, 4x4, 351w. I just bought some full length headers, the http://www.summitracing.com/parts/HOK-6912HKR

    The questions I have are:

    1- Where would be the best spot to put in the o2 sensor?
    I was thinking right in the middle of that mangaflow y, but is it all hollow inside?

    2- Do you have any schematics/instructions/tips for this?

    Thanks so much man

    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.
