If you don't go crazy with a steep rear gear, and drive it sanely, upper twenties is typical for a stock 5.0 and T5 on the highway. City driving is typically reported as mid to high teens.

Where's the fun in that?

Ok thanks for the post, that was the info I was hoping for. When/If I get a mustang I plan on doing the 5.0 swap with the 5 speed along with mega squirt and a multi port injection intake and Holly EFI 1000cfm carb look alike.

Hopefully with some lean cruising mixtures and a mild cam I can still get low to mid 20's on the interstate and high teens around town if I take it easy.

 

is there anyone on VMF that has actually done a mega squirt?
