You also need to remember that 180 hp on those carbed engines was a "factored" net rear wheel horsepower to beat insurance and government mandates. Most of these motors easily put out a true 200-230 hp and it didn't take much to make a bunch more without a tuner.

shhhh that is suppose to be our secret. i can't afford my insurance to go up if the insurance company got wind of that. lol

Lmao that's funny

1999 3/4 ton 5.9 v8 360, I sadly get consistently 8.7 mpg, and that's basically just driving around town and to school. Its basically all stock, but it's got American racing rims, dual rear exhaust, brush guard. I'd be ecstatic if I could get 12 mpg out of the old girl! But.. I'll believe it when I see it. It runs like a champ, I guess I'll hav to live with the mpgs! Any suggestions on how to get that mpg up, would seriously be appreciated!

have you repaired the plenum? could also make sure your tires are inflated properly. even being a couple of psi under inflated could make a mpg difference.

my last top up was 13.2 mpg

Well I had my local mechanic make sure the plenum gasket wasn't out because I thought the same thing. According to him it wasn't. And yea I always try to watch the tire pressure, oil, ect.....

Maybe, but I think power and torque is superior on builds with that kind of mileage.

I was averaging 14 with 35" tires and stick 3.55 gears.

Now that I switched to 33" I am getting about 10 mpg with stock gears!

Sorry guys, I did not know I was in the wrong forum for HEMIs. Yes, I do have the new Crew cab Longhorn with the 5.7L Hemi. Love the power and the room! John

i get like 8.7
