come on Curt, I've got more confidence in you than that!!!....sacrifice?, not really sure, I can tell you what I'm hoping for, not concerned about fuel milage(its an old truck, they are supposed to be thirsty)just wanting a nice "sweet spot" that will perform well with my drivetrain selection,good low to mid range TQ, and HP to about 4500 revs.is that out of the question? HP of 250-275 range would keep me smiling.
