35-255-5 Cam
I recently rebuilt my 351W in my 92 F250. I put comp cams 35-255-5 cam in it. What have other poeple experienced for gas mileage with this cam? Did you have a drop? I know that my motor will suck gas until it loosens up. I was just curious. Mine just seems to really be sucking gas right now.
Thanks.
Thanks.

I really like the cam. It has a very good power band; down low, right where you want it. I pulled a K5 blazer 90 miles at 60-65 mph with no problems. I think my mileage will get better once the engine loosens up. I think I was just panicking. After all, it has less then 1,000 miles on it.

the oil is pretty wierd looking, epecially after the first 20 minutes. I have been running GM EOS in there still, too. I figure that can't hurt anything. A little extra protection should be good for it. I also run Rotella 10W30 since that has a better add pack in it.

I figured I would update the thread that I started. I took a trip this weekend with the truck. With a mix of city and highway driving, I got 13 mpg. I think that is pretty good for a HD F250 with new engine. I figure I should be able to see a 1-2 mpg increase after it is broken in.
