hi all, i need some info on a 2004 chevy, it has a 6.0 liter engine, i have an 06 express with a 4.8, i was wondering how much more fuel the 6.0 will use compared to a 4.8 ??
Yeah but Ol Yeller is a 5.7l.....last year before they brought the 6.0's out. Also almost all GM cutaway's have the 4:10 rearend so keep that in mind as well.
