completely depends on the setup. my buddy's 80something f250 has a 351 and it gets 12mpg highway, but its got 4.10's, weighs 5500lbs, and is tuned like crap. a well tuned, fuel injected 351 that breathes well should do fine on gas, shouldn't be much worse than a 302
I have a 351 in my 88 mustang and had 302s in larger cars they dont seem to be too much different on Gas I love the performance in my 351w it Has fuel injection. The engine is an older one from a Cal. Hiway patrol car. Most likely 79 or 80ish. Depends a lot on how you drive it. My problem is that the Tank must be real small not a lot of gas goes in there about 10 gal or so.
Im replacing my speedometer cluster. I have everything out except the headlight switches on both sides, I fooled with the one on the leftt and got it out but then the wires hold me back from getting of the cover. Im thinking it wants to go in instead of out. Is this correct? Any Ideas.

yes i would say that the efi 351w would get pretty good MPG. Mine is a carb set up and I get decent economy for a car that runs in the 11's. I guess Its hard to have both.
