Okay so its no shocker that the majority of threads here are dedicated to the Ecoboost and the 5.0L with a little 6.2L tossed in now and then. Even though I didn't buy one myself I'm still really curious how those 3.7L's are doing.
How are they for power in real world? Hows the mileage on them? Anyone worked one hard or pulled something decent with one? Any modded engines out there? If so what did you do? Lets get some info going on these 7000rpm screamers!

I have the 3.7 and it has handled everything I have thrown at it exceptionally. Mine is rated at 17/23, and right now my average MPG is 20.1. I drive about 50/50 city/highway, so it's about right. 302 HP is enough for me, I will never need anything more than that.

It has great power and can easily do 22.5 - 23 MPG on the highway. I've done a couple thousand miles on the highway for road trips and the MPG is what they claim even with the SCREW and 3.73 gears at 65-70 MPH.

The city is another story. I have to struggle to get 17. If I drive 'normally' without mashing the gas pedal I'm at about 14.5 - 15. That said MPG isn't a deal breaker for me and neither is the money. It gets the job done nicely, less parts to break, 2 less plugs, and plenty of room to do engine work, etc.

I have hauled light to moderate loads with no problem. Will be pulling an enclosed trailer on my next trip. These days the remaining midsize trucks on the market don't compare to the F150 3.7.

My main gripe is SCREW 3.7 cannot be bought with 4wd.

Even though i wish i got the 5.0L I do love my 3.7L and have some plans for it. I heard they like turbos

I love my 3.7L! It sound great, quicker than you think and gets good mpg. I've been thinking about mods to make it a little quicker and increase the towing capacity. Anyone have any ideas? I don't tow/pull that often, just would be nice to know that I could if I wanted to. Has anyone pulled a 16' enclosed trailer, approx. 6,000 lbs? Thinking about getting a 5 Star Tune, anyone have one? Thanks for the thread on the "entry" level engine!

Yeah I figured it would be good to have a thread about them, like I said I want to know how this mill is doing, I don't think its getting enough attention! Hopefully there's lots more good info out there

From what I read, all 3.7 come with 3.73's. After only a couple weeks with mine, I can tell you it does not lack for power or acceleration. My first tank got 18.5mpg with almost all suburb driving. I will be hitching up the boat and flogging soon.

Agree with above poster, the midsize trucks( Colorado, Frontier, Tacoma) do not come close in room, and driving comfort, and they don't get any better mileage. I had a 2005 Colorado Crew 5cyl, after a couple years, I could not take the rough ride and poor mpg.(22mpg best highway). Got a 2008 Frontier Ext. Cab SE-V6, nice truck, had a better ride, but was a gas hog and had some nagging problems. My son has a 05 Taco Access cab with a 2.7 I4. Best highway mpg has been 22 and the road noise is bad even with street tires.

My only issue is that it doesnt have enough mods on the market really. Hard to find parts and anything for it! Cai and exhausts are scarce!

I have seen the 3.7L trucks with 3.55 and 3.73 gears. Some with and without a limited slip. I drove both and there was a distinct difference. I ended up with the 3.73 limited slip. I have installed 20x8.5 wheels with 275/55/20 tires and can tell a difference with the 1" larger diameter tires. This is still my first tank of fuel and am averaging 15.6 with 100% city driving but the truck only has 300 miles on it. I have a 5 Star tuner and an Airaid intake on the way. I do have to say it is strange to have a 7K redline in a truck.

Yeah, the first time I test drove one and I saw and heard that thing rev to 7000rpm I was pretty shocked, had never seen a truck come close to that before!
