OK your guys thoughts:

What do you think would be better mpg wise:

6.2L Raptor Crew
or
F250/350 SD Crew w/6.2L 3.73s/4.10s

I'm talking 75 - 80 mph down interstate cruising for a few hours.

I've read multiple posts on 6.2L FE both with Raptor and SD and I suspect they'd be close, with edge to Raptor.

Any thoughts?

 

Just for comfort i would go with the Raptor.

 

Thanks, but I'm well aware of the +/- between the two.

 

My 6.2 averaged right around 14 cruising between 75 - 90 for some pretty solid stretches.

 

thx
