1992 Ford E350 Cuttaway Class C RV with 460 CID Cubic Inch Displacement. Spark Plug Removal....

Looking for any tips on how to successfully install new plugs on this 460 engine. The vehicle is just turning 70,000. I plan on installing new MotoCraft OEM Original Equipment plugs, plug wires, distributor, rotor and Cap. I remove the back 2 plugs on each side . Those removed must be the 1992 originals as the correct gap is supposed to be 45,ooo gap. The plugs I just removed are at 70,000 gap. Quite the change.

Here is my dilemma. I am s trying to access the front four plujgs on both sides. The OEM heat shield do not allow space to extract plugs. I am working on removing the shield, but cannot see how to get between the firewall and the exhaust manifold. Once the shield, is off, I am Any type of special wrenches to make project possible.?. Please advise if you know of a special solution. If you have suggestions I would appreciate the help. Thanks

Take a look through the wheel wells to see if you can get the plugs from there. Might be doable with a universal plug socket and the right combination of extensions and maybe a universal joint or two.

Exactly what Matt T said.

If possible, use a jack on one side or the other to raise the frame (and thus the body), while leaving the wheel on the ground. Might give you that little bit extra space needed.
