I have an 87 GT I am considering using an Explorer intake with non EGR style. What is going to happen as far as check engine light and running wise one I use this intake? I do not plan on a tuner or any chip to disable anything. Just a budget ride with a few goodies.

it will drop your fuel economy. the external EGR that was used with the later Exploder intake actually works better than the internal style. i lost like 5 mpg ditching EGR and the vehicle wasnt any quicker without egr.

It's most likely going to throw a code and your check engine light will come on unless you aren't running a computer controlled setup, i.e. a carb.

I have found that my 1987 and other friends HAVE it? I was told only mass air cars? Anyway more concern is on driveability with poor MPG for this daily driver. This explorer set was cheap but may not be worth the hassle.

Earlier exploder intakes like what you have do have internal EGR.

Have wondered from time to time if an external EGR set up could be adapted to the newer exploder intake to an older vehicle or an intake like the victor 5.0

That is a HUGE drop. Like 20-25% on a stock car. It coudln't be that much unless other factors were at play.
Ditching EGR is like disconnecting vacuum advance from a car the before EGR was used from the factory. Depending on ECM it would limit advance from say 40* or more at a cruse speed to less than the 35ish* available at full throttle. If you were to see and understand the ECMs programming it would become evident.
