I was reading all the post about injector switching for the 4.0. I did a search found out 5.0 and neon injectors would work. I have some injectors for a 1990 ford 351/5.8 L motor, came out of a 1990 ford f250. My question is will these injectors work?

 

Im not positive, but I think they would be way too big (run rich)
Ill try to find the specs and find out, If someone else doesnt before I do. lol

 

What color is the top plastic part of the injectors you have from the ford?

 

Im not excatly sure, its dark here now or id tell you plus got 6 inch snow outside. Ill find out first thing in the morning and see

 

If they are yellow or some look yellowish orange, they are #19 injectors which would work fine. If they are blue, they are #24 injectors which would be too big for an engine that hasn't been stroked or had other major performance mods.

 

24's can also be white. i THINK that non lightning/cobra 351's had 19's in them, but dont quote me

 

if you run bigger injectors, your gonna need to tune it. for my z i used niztune, not sure if you can tune these computers????

 

AFAIK you dont have to retune it. Just clear the computer and let it relearn the fuel map.

 

aw **** forgot this where map and not maf
