1998 Ford Explorer Specs - CarsDirect
215 hp...
I'd be interested to see the torque range in comparison with the stock e7's. If those heads flow better there has to be a reason why the HP rating is only 215. What gives with that?
I know there was one in 94-95. I think they were ported, or at least cleaned up, but the car made like 301 to the wheels.In fact, I think there is a 300rwHP on P's thread floating around.
In my humble opinion, GT40/GT40P heads are not worth it. By the time you get done buying the heads, upgrading the springs, and sending the heads to the machine shop to be decked/ported, you are close enough to the cost of a set of aluminum heads to make it worth waiting a little longer and just getting the aluminum heads.
Just my opinion and why I have twisted wedges.
