Explorer engine questions

[GWL]

what year explorer engine can be used?

Mid '97 to 01 Explorer or Mountaineer. They changed in early '97 so you can look for for 4 lines cast into the head, front or back.

That is a GT-40p head which is the best flowing Ford stock head.

These engines also have a better intake system than the earlier Mustang engines.

I would consider changing out the cam and valve springs. Trick Flow makes a mild cam with valve springs that do not require any head modifications.

I do happen to have some engine parts for sale:

I wouldn't say they are not recommended. Besides changing the plug angle, the combustion chamber is a little different which will also increase the compression ratio. I don't know what the HP/Torque ratings would be for each engine. There has got to be some comparisons out there somewhere. Remember too that the Explorer and Mountaineer have cams that are better suited for a truck engine so stock engine ratings would not be a fair comparison either.
