Buying new v8 or v10 engine help

[Gh0ztkid21]

Nice not bad at all, whats the best gearing for the v8 and best gearing with v10 for fuel milage at cruising speeds? I have located a v8 quigley 4x4 with 3.73 gearing and 295 65r18 tires.

I'm guessing you have a v10? That's a bummer for milage. I was hoping better then that but have heard many guys say that's the average with a few here and there getting as high as 13mpg.

The only reason I might opt for a V10 is the transmission. The 4 speed feels really old after my experience with the Torqueshift behind my old 6.0.

Just fyi you can get a 5R110W (TorqShift) behind a 5.4 . My box van cutaway e350 sd has one.

Interesting. I'm no mechanic by any means so would probably cost a pretty penny to do the swap but that's good to know down the line if the tranny on a v8 ever went.

You would probably have to swap the computer and maybe the harness also.

First off I have never driven a v10 E350 but I did go from a 2011 F250 with the 6.7l Diesel that was deleted and tuned. The thing was a beast and I definitely loved the horsepower and 16mpg gas mileage.

With that being said I now have a 2014 E350 5.4 RB averaging 14mpg stock with tiny tires and I love the feeling of just being able to enjoy the drive and taking my time. I think these vans are great for going places and doing things and mine isn't even setup like a Sportmobile (yet) and wouldn't trade it back in for the horsepower on the truck. So my opinion is this, unless your going to tow a lot then the V8 is fine, yes its not going anywhere fast or with an amazing amount of torque but its enjoyable and has done everything I need it to do.

I am also interested and going to pursue adding the 5R110W once I get some other things knocked off my checklist.

Yes, it was optional in the cutaway, but not even offered in the vans. That said.... one of those AeroCell or Turtle top fiberglass bodies is starting to look awfully tempting for a camper body

Thanks I found a 2014 5.4 v8 with 3.73 gearing and 295 65/18 tires I wonder how that would be with fuel milage, and what kind of rpm it will be while cruising at 70mph. Wonder if that setup will put any additional strain on the engine being those tires are 33" so that's a lot of added weight and drag and I'm not sure how that gearing works out for that setup. Anyone know anything about the topic?

*fuel mileage quotes read on the internet are always high. Honest people quote their mileage and the internet converts it to 20-50% higher. So far, I see two people in this thread who somehow avoided the airwave traps. One who said his 5.4 got about 12.5 at average freeway speed, which was my experience exactly, but usually only about 12. Another with a V10 who gets 8.5-9.5. Let's see what the airwaves convert my numbers to.

My 5.4 got 12
My 460 gets 10

Really, total ride height (tire + suspension lift), and what's bolted the outside, have more affect than what motor it has.

3.73 gears are way too tall for 295 tires. That will require lots of torque converter work to launch from a stop, and it probably will struggle to stay in O/D on the highway, especially if it has a bumper or rack. Both of those issue will make lots of extra heat in the transmission.
