Re: carb/gas mileage
That's some pretty poor mileage you got there !
That equates to @ 3-4mpg !!!!!! Even an old 360 can get better than that...sufferin !!!!!! There is obviously something wrong somewhere, I'd agree with you and suspect the carb, no doubt. You realize that at that kinda mileage you could pay for a re-manufactured carb pretty quick if it yields you better mileage.
I'll help you out, where I can, as I'm pretty good at getting a few more mpg's outta anything. Does your set up have a vacuum distributor ? Is the vacuum advance hooked up ? Set up correctly the vacuum dies nothing to hurt performance and helps out mileage in a very big way. Secondly, do you have an aftermarket coil on there yet ? If not, get one and open up the plugs to .050 to .060. That punched up my mileage more than any single thing I've done.
Don't forget maximum tire inflation, regular oil changes, synthetic if it ain't leaking(and you can afford it). At one point, in the Arctic, I had synthetic fluids everywhere in the old Bronco.
Try that, but buy a rebuilt carb fast ! and first. There's an outfit in Winterpeg that supplied my jobber with a beautifully remanufactured 1974(pre-emissions)800 cfm Thermoquad for my Mopar for $235.00 Canadian. They're called world or global or something, but they did a great job, try to get your jobber to admit they know them and order one up.
If you want a hand setting up your vacuum advance tailored to you own truck, let me know, I've got it nailed foolproof [img]images/graemlins/burnout.gif[/img]
