    another Ford converting

    ok Im hooked on doing this
    67 f 100
    71 (335) series 400 engine 9/1 compression from a galaxie 500 C6 trans mission

    my cousin owns a wrecking yard I have my choice between a 91 1500 pick up and 93 1500 conversion van to pull the wiring from
    both have 350 engines

    I plan on using a plug and play distributor http://www.ebay.com/itm/Big-Block-Fo...a094d9&vxp=mtr

    that uses a GM big cap will this work?

    is are the injectors from a 350 big enough? or will I need larger ones?

    my fuel tank does not have a return line Im going to have to get creative suggestions please
    will I need to run 2 ox sensor's ?

    my guess is that trans is no issue? speed sensor off cable to speedo

    what am I missing?

    I think I would convert a Ford distributor to the GM 7 pin HEI Module. The Car Craft link ( http://www.carcraft.com/techarticles...ion_to_gm_hei/ ) shows a Ford distributor converted to a GM 4 pin HEI module. The same procedure is used to convert to the GM 7 Pin HEI module.



    The Ebay distributor won't work.

    I understand what your saying. I was thinking the junkyards would have everything you need, GM and Ford parts for budget prices? Maybe not?

    The ebay distributor is set up for plug and play use on an engine with a carburetor, it's not plug and play ready for a TBI fuel injection system. The ebay distributor uses the 4 Pin HEI Module with a vacuum advance. The ebay distributor would need to be converted to the 7 Pin HEI Module. The ebay distributor will need the vacuum advanced and springs removed along with the advance plates welded.

    It sounds like Dave can get you straightened out on the distributor side of things. I would recommend going with the '93 harness and PCM. For fuel pump/tank in a conversion, I have done this on 3 vehicles so far and it works very well.

    I would also recommend the 93 ~ 95 TBI PCM, but usually requires a Vehicle Speed Sensor (VSS). The budget choice would be the 1991, which can be budget setup to operate without a VSS.

    now that is a cool idea

    the standard F100 tank is behind the seat Im thinking of relocating behind the rear axel by using a early 80's f150 rear tank

    can some one explain how the computerized distributor advances?

    The quick answer (not 100% complete) is the computerized distributor does not advance / retard the timing, the computer uses a spark table to advance / retard timing. In my way of thinking, it's like advancing / delaying when the coil actually sends spark to the spark plug. There are better explanations, but that how it works in a nutshell.

    That's a nice looking harness. It should lay out over the engine with everything coming out of the harness in the correct area where it needs to be connected. You've also already got the firewall pass-through plug and then it hides all the other parts inside the passenger compartment. The only complaint I would have is the use of an unheated O2 sensor.

    The EFI-connection harness has a common harness and then little wire harnesses for each connector all split off at the same time. I can't see that installing as nicely. Also, no firewall pass-through plug and if you did pass that main harness part through the firewall then the OBDI plug would be in the engine compartment. It also looks to use a single wire O2.

    Just mentioning the single wire O2 because many people doing TBI swaps are using headers which don't play well with a 1-wire O2. Having a heated sensor already in the harness saves having to add the wires. At least the wires would be there, even if they require extending for some applications.

    Adding heated O2 is simple and low cost. Available add on kit conversion, see pics, or install into to the harness before shipping. It always a challenge to sell an aftermarket product ... cost vs. features. Most potential buyers look at the price first, then the features.

    we have a winner its starting to look like Ill be able to do this for less than I thought Ill pm you when Im ready and leave ebay out of it

    I wont be using headers so I don't think I need to worry about a heated o2 sensor

    next question ****
    will using this on a engine 50 CI larger affect the ecm? will I need a chip from the beginning?
    Im not looking for high performance Im looking for easy starting and economy
    also with dual exhaust will I need 2 o2 sensors?
