What kind of gas milage do you get out of your 360.

I'm getting a 360 and auto. tranny out of a Jeep Wagoneer installed in my CJ7and was wondering what kind of milage I would get out it when I get it back. If anybody has a setup similar to this let me know. Thanks

I have a 360 with a t-18 4 speed in my cj. Right now, it only gets about 11 mpg, but I still need to fine tune the spark curve. The engine is also not broke in yet. I,m hoping it gets better.

Gas Milage

I have a 85 CJ7 with 360, Auto Tranny, 33 tires with 2.73 gears. I get 14 MPG on the highway, little less in town. I am sure it will go down a little when I put in 4.10 gears.

I,ve got 32" tires with 4.10 gears. Maybe 11 mpg is as good as it gets. I have a 600 cfm holley( vacuum secondary). I,m thinking of trying a 470 truck avenger; I just want torque, and better fuel economy than 11 mpg.

Gas mileage, it's not something you talk about when discussing a 360. I probably get about 9mpg, going down hill.

Having an AMC V8 in a jeep can be kinda cool, and give you abundant power IF you really need it. BUT...there's a price to pay (no pun intended). They are gas hogs!!

If it's your daily driver, re-think this decision.

My jeep is just a nice day, top and doors off, crusin' vehicle, so I wouldn't trade the 401 for anything!!

BTW...I get 8-10 mpg.

I have a 360 w. T176, 33" BFG and 3:54 Gears. It is newly rebuilt with a 600cfm Holley 4bbl. I tach roughly 2400 at 65mph and get between 14-16 mpg. I do not correct for the tire size or it would actually be a little better.

In town, about 12-14 is typical. Having the power is fun, but only a 15 gallon gas tank means I have only a 150-200 mile range.

tbi injected 360 with hei, jeep has 4.11, 35"s, and 5" of lift. I get around 15 to 16 when I stay out of the throttle, but with a 4 speed if I go over 55 my rpm's are around 2,600 so its still about 15 to 16.

I'm not to concerned about milage, I was just kind of curious. Thanks for all the input.

If you want to go really big, get a 401. My 76 Waggy has the 401 and automatic. Mileage = 10-11 maybe.
