thanks for the replies. im runing 10.50x31 tires,<br>not sure what gear ratio is? 65 mph at 27-2800<br>rpm. changed o2 sensor...numbers not in yet,dosnt<br>look any better though! ??? anyone done away with<br>the efi system and gone the old fashion way? ie<br>carb and intake? thanks again! gashhog89

i am running a edlebrock 600 on my 86 ford bronco. i have 33's and 3.55 gears and i get about 14 highway and 10 in the city. I also have headers and dual pipes. so thats helps too.

14 mpg sounds good. did your 86 have the efi<br>system? if so how did you get around the computer<br>systems, ie, tp sensor, O2 sensor and all that<br>stuff. nobody wants to talk about dumping emission<br>stuff but 8-10 mpg isn't to friendly either...<br>wallet pollution! isn't efi supposed to be more<br>fuel efficient. thanks gashhog89
