- 99 Mounty 5.0
So, truck is a 99 Mounty 5.0 2wd. Will be lowering it 2" this week and hopefully installing my TM headers soon after (and full exhaust after that). The end game is to improve MPGs, but looking to add some "fun" to the truck (ability to pass a little easier without having to drop out of O/D and then drop a gear). Will either be going with 255/55R18s or 275/40R18s for my 18x9s.
Question is: Will going to 4.10s completely negate everything I'm doing MPG-wise or no? I understand that it's only a "step" up from the 3.73s...so my thought process is that it won't be but a few hundred RPMs higher...but would also rev up a little quicker. I've gone from 3.27s to 3.73s in a mustang before and saw little to no loss in MPGs...but it also doesn't weight 4600 lbs.
Thoughts? Opinions?
