oh yea.... the story was they lost it on a dirt road... but hey i picked it up for 650 and the motor runs great... cut the frame and all the supports and pulled complete drive train out for swap... even kept harness... i will be building my own harness and will be gald to put up wiring diagrams as i go.. This is what remains of the Explorer... I will be cutting down factory harness to create a standalone for maverick

Plans are: Cam, springs, and lifter swap got a used X303... Also not sure if i should use the Edelbrock performer intake or stay with the GT40 i was told the edelbrock was worth about 35 hp over a stock intake but not sure if that applies to the gt40 explorer intake... Have a proformance power Throttle body and a big shot wet kit for fi cars to install later... will be pushed by a built c5 trans and 410 posi 8.8 rear... OHHH picked up all parts in pick for 150.00

looking for a nasty street ride... Got a X303 cam 248/248duration and 544/544 lift hydro roller. I already have the edelbrock intake and power performance tb i picked it up with cam all for 150.. so should i gasket match and do some hand porting on edelbrock intake? also is it too much cam for the gt40 heads??? i will do a spring job to hold lift...Dont Know much about intake... though it looks like it bolts to a stock lower to me tho....

The Edelbrock uppers must be used with the matching Edelbrock lowers. Now if memory serves me right, there are the performer, RPM, RPM II, so several Edelbrock intakes. If it is the straight performer, having tmoss port the Explorer GT40 copy will not only get you the low And mid power, but also the performer's top end. As far as valve springs, contact Edelbrock for a specific recommendation and check for piston to valve clearance. I bet it will be OK.

You can down load a factory diagram from ford ,they have it on CD also .It is actually simple ,there is only 4 or 5 wires that run the motor .
If you have the full computer vehicle ,where everything goes through the computer it it a total night mare though because of all of the extra wiring .I did it in 1985 ,used a T Bird 5.0 into my 78 Ford pick up using the Ford CD .I made a diagram but i can not find the thing ,but it has been a loooong time .

There are many Efi harnesses out there, rjm is one.

You are going to have big header issues running those gtp heads in a maverick. I suggest you go to maverick.to forums and see how others made out work.

That intake is perfect for those heads, and the throttle body too, it's a 65mm.. The throttle lever can be nodded for the throttle cable.

That x cam is not the best match. A TFS 1 cam works best, or an Anderson cam which was designed for those heads.

Make sure you change the valve springs, they're horribly weak

hey fella's i know its been a while but im just getting stuff lined up and have finally started on it last week.... meaning it will be holding up a bay in my shop untill shes ready for the roads....

So i still have the gt40 motor but ive decided to go a different direction.. I now have a 5.0 short block... IM running a set of windsor jr heads and the x303 5.42 camshaft.... I did hit a snag with the motor the block has been zero decked and the pistons were not fly cut for larger valves in heads.... SOOOOOO after long consideration ive decided to order me a set or .060 head gasket shims to give me the clearance i need... ILL post a few pics.... also i did locate a t5 and i was able to go thru it and get it cleaned up and painted... check my pics fella's..

I have a 5.0 I had to Change cam and use a head gasket shim to get my clearance bc someone had zero decked the block.. so I went down from x303 to this cam and installed a .020 shim along with gasket and new arp bolts.... Now I'm back to engine bay while I wait for parts house to send me the correct clutch set.. i purchased one but it was for a tko trans and the spline count was 26 instead of 10
