your method is the best way to measure, its not far-fetched, the 5-spd and 2.73 REALLY help us out, @ 75mph im a tick under 2,000rpms

this is so funny cus as some know im on the 4banger forum alot...they are always telling noobs to turbo a 2.3l instead of a 5.0 swap cus the will get 26-30mpg in it,lol, even if thats true i think its alot cheaper to go 5.0
and 30+ in a carbbed motor! wow

if you think about it its makes sence the primary barrels are pretty small dont put out a lot of gas its the secondaries that really pull the car. so cruising on the highway your just working off the two primary barrels pulling enough gas to keep momentum. now its when i romp on it that i get about 12 city
