Thanks again JJ. And I appreciate the congrat's on the truck.

I totally understand, plus no telling how long fuel prices will stay where they are. I was going to do a gear swap on my truck, but kinda enjoy it running about 1800 r's ~70 mph. Makes it keep about ~17-19 mpg on the highway. If I went to 4.10 or so, I wold definitely lose on the hoghway mileage. I drove a newer 4.6L F150, man they run real good. I just think about the whopping 145HP my 1996 F150 put out (4.9L I6) and loved a 4.6L

Good Luck in your performance venture.
