Anyone have the new Ford 7.3 gas with 3.55 axle ratio? If so does it work out for a 2500# TC?

Huh?Umm yeah, I mean, it’s got more than enough snort to haul around a TC.

If so does it work out for a 2500# TC?I don't have one, but I would say no, especially if you also plan on towing anything or driving in the mountains.Flat ground, no towing, a TC which actually weighs 2,500 lbs and plenty of time to get where you are going, probably OK.I once drove two new F350 SRW V10 gasser Fords. One had 3.55 gears and the other had 4.30 gears. The 3.55 was a dog; the 4.30 was a rocket. I got out pulled by a 4-cyl Camry on I-65 in downtown Birmingham in that 3.55 truck.

I don’t but if it has the 10 speed transmission my guess is it would be fine even on mountains if it is rated for enough payload. Ford would probably have no advantage in producing a combination that can’t haul 2500. So, I’d look to see what payload it’s rated for.

Right, with the ten speed tranny this will be fine. I think I would go for the 3.73, but that’s me.Will you be towing anything behind the TC?What is your goal for the 3.55 ratio?IMO rear end ration has very little effect on mpg. Driving habits will have a greater impact.

Just fyi, my 4.30s kill MPG over 65. Yes, 4.30s are pretty high, but still, they have a huge impact even on cruise control. The RPMS are much higher. In case you didn’t notice, I have 6.4 diesel.

new Ford 7.3 gas with 3.55 axle ratio, does it work?

I would go with a 3.73. I had a Chev 2500 6.0 years 3.73 ago and pulled a 4000 lb boat all over the NW. The 7.3 will have a lot more power and also has a 10 speed transmission. I think the 3.73 will be much better mpg while the 4.30 will have more acceleration and use a higher gear.

I’m considering a new F350 7.3 gas Supercab SRW longbed to be paired up with something like an Adventurer 86fb or Wolf Creek 850 and tow my 3500 pound boat and trailer.
3.73 or 4.30 gears?

Maybe drop a water wheel in the creek and hope they are not in drought?

That’s a great idea, but I think I can make it there on the 200 mile range if I drive a bit slower. ;) I’m not sure how I’d recharge at Yellowstone though. Only one of the campgrounds in the park have hookups. :D

Just joking because I don’t plan to buy any new vehicle. I’ve outgrown that hobby. I just wish I had a couple of decades ago.

Nuts to electric. The big rock candy mountain will own all the mines for those batteries in short order. I want little hydrogen power plants!

You'll be parked for 8-10 hours at a recharge station every 200 miles, solar would take days....
