I have a 92 f150 with a 302 in it and e40d. I found a 98 explorer with a set of gt40p heads and intake with all the parts to do it and i wanted to know what it would take to put all this together. I go to UTI in AZ. I have orange top injectors with new fuel pressure regulator and 3 new injectors. i think i have the speed density air system. Also no rear cat or muffler there is no backpressure issues. It also has a set of short tube headers on it. What i want to know is pretty much all the details. I am planning on a e303 cam when i do all this if its a good match.

Will I have to switch to mass air flow or just use my speed density parts?
( the explorer ecm wont work, i dont think it has e40d)

Will the air crosover tube for the air diverter valve in the back of the cylinder head match up?

Will I need an adjustable fuel pressure regulator and larger injectors?

Will my short tube headers bolt on the gt40p heads?

Can I run 1.7 Roller rockers or 1.6 without valve train issues.

Will stock gt40p heads have coil bind with 1.7 RR and E303 cam

Will the motor idle with this cam?

Will my accelerator cable and cruise controll cable work?

Basically i need to know everything and any information would be great. I plan on doing all this at once and could use any info. Thankyou

 

i don't like the gt40p heads because you have to use different headers since the spark plug location was redone and the wires will be really close to the headers and melt, in order to run an e303 cam you will have to switch to massair not sure about the injectors since i did away with my fuel injection when i got to that level if you have the e303 cam use 1.6 injectors the cam is plenty big with out the extra 10% lift added in be sure to use springs that are reccomended for that cam and they are alot easier to change with the heads off of the motor with mass air i think it will idle with that cam cruise control and acceleerator will work if you use the stock intake and throttlebody but with the e303 cam i think you should run a bigger stall converter which can be had used on ebay for pretty cheap

 

Yes if you use that cam.

No I don't believe the P heads are drilled for air injection.

No.

Yes.

1.6 yes, 1.7 no.

Yes.

No.

Not without a custom bracket.
