my modded ecsb 5.3 got better milage than my scsb 4.3 and hopefully my 5.7 will do better too. the only thing that the 4.3 has going for it is its decent power numbers and the fact that its dependable as hell. i know atleast 3 people who have atleast 250,000 miles on their 4.3's with minimal maintenance. change the fluids and those motors will go forever!
