Thats about the average,, you didnt mention if you had a 4x4, but at any rate,, 360 engines, where VERY heavy, alot of cast iron, for no reason really. You can have differant gears installed in the rear end, which can help a bit, but then your pulling power would be reduced.

That very heavy myth has been around forever. Fe's are lighter than 460's, with aluminum heads and manifold they weigh LESS than the stock 351 windsor, no boat anchor. Their Y block configuration allowed cross bolts which is one of the better main cap retention designs as it resists side loading better than 4 bolts going straight into the block. They were also one of the first engines to use thin wall casting techniques before other manufacturers. I can and have picked up a bare block and put it in the back of a pickup.
But to get back to the thread, the best milage my 360 has seen is 11.83 I average just over 10 right now. My dad managed to pull of 15 with his. So it can be done.
I used to have a 1991 full size Bronco with a 5.8L (351) and it would only get about 11-13. It had fuel injection, an overdive automatic, 3.55 gears, and 31x10.5 tires. The best it ever got was 14.7 which was all highway going 57 mph. A buddy also had the Doge version - Ram Charger - with a 360 and that was all he could get.
[updated:LAST EDITED ON 14-Dec-01 AT 11:57 AM (EST)]I get about 11 mpg with my '74 F250 4X4 (360 2bbl with headers and duals, 4 speed, 4:10 gears, and 33" tires)
Be happy with 11-13 mpg. I get around 6-8 out of my '68 F250, 390, 3.73 gears, but then again I only drive it about 100 miles a month and they are very fast miles, if you know what I mean.
well my point was, that a stock 360 has more internal head and exhaust manifold casting areas than isnt all that necessary really. they just dont breathe to great,, but yes, after market manifolds and heads are an improvement in any case..
I get between 6 & 8 mpg in my '75, depending on whether or not I'm towing. Does anybody that's getting over 10 mpg and running a Holley 4-barrel know what jets/power valve/secondary spring combination you've got in your truck? I work out of this truck, so any mpg increase would be wonderful.
