    IMHO, If you're on the "cheapo", save your $125 and put it towards something else (gears, carb upgrade, headers, other).

    That's just my :2cents:.
    (anybody have any money I can borrow? :( )

    As Rick stated, if you are trying to do it cheap and you've never done it before, you're better off spending $125 on something else...like a good used carb.

    IMO, you cant use "cheap" and "EFI" in the same sentence.

    You can use the OEM harness but you'll have to do some serious work to retrofit it into your car. Then run a fuel line (for return). Then install a pump. Throttle cable wont work, so you'll have to have that too. And a thousand other little piddily things that will have to be done. It makes it a little easier if you can get the whole Lincoln and use parts off of it, but keep in mind that the Marks (depending on year) were speed-density EFI--and IIRC, were only about 200 HP at the most. Speed density EFI means you'll have to use the Mark's camshaft more than likely. And if it's a roller and your Maverick engine is an early block, you'd have to retrofit some hydraulic roller lifters (not cheap).

    Lots of stuff to think about on an EFI swap. Do-able, yes definitely and it's worth it. But not cheap.

    If your car is running good (no misses), I'd go for a set of taller gears first (again, just my opinion). I believe you'll get more bang for your buck.

    Besides, if your car is running poorly, odds are that it isn't the intake (unless it's cracked - which is unlikely).

    Good luck either way you go.

    well now i wouldn't say that EFI cant be cheap.....

    ive bought two EFI setups from junkyards which included intakes, wiring, ECU & everything for $25/setup. i also have a TBI setup that i bought as well for $25. so if a person is dedicated to making their car a 'fuelie' then it can be done cheap but you have to look around. just my thoughts... :)

    He has no knowledge of fuel injection systems, obviously.
    First, the Mark VII is a speed density system and is easier to adapt.
    Second, the 302 has the wrong fire order to be compatible with the EFI, without changing the camshaft to one with a flat tappet, the correct profile and fire order..
    Third, a complete new fuel delivery system has to be installed.
    Forth, the distributor has to be changed.
    And there is more.
    It's not as simple and cheap as he thinks and without understanding-yet..

    have consideration for people before making such a remark. most call it common courtesy... no offense meant but i think u may have worded that statement wrong. :naughty:

    as for the subject at hand speed density is easier to work with(agreed), get EFI from an 86-88 LTD or so and keep ur 302 firing order so u just have to change the cam gear on your distributor, you can use your existing fuel system with minimum modifications. so for the most part, it is pretty simple as far as installation goes ;)
