Last dealer parts guy I spoke with found that the new price doubled in the past couple monthes....I'd take a dozen...

Indeed Barry! Spoke with my parts guy today and he confirmed the huge price jump Dealer cost has jumped from 38.00 to 76.41 
New price effective October 1st. I just bought a couple 3 wks ago and paid the 41.xx each.

I can still get them for you but price 84.05 Ea  I had no idea they had recent price jump!  R

A few wks ago when you asked for some I called dealer to see what my cost was. WHen he said 41.xx ea my cost I ordered a couple. Was meaning to get more but kept putting it off.

Just so you know Ford does not plan on producing more and when these are gone thats it.  They did the price jump because they are running low on last batch. They will be obsolete soon.

Joe, The 3.5L EcoBoost has so much torque along with the wonderful 6R80 6spd trans it easily does wonderful with the 3.15 Gearing. Another friend just bought one 2 nights ago (I helped negotiate a good deal) It also has the 3,15 gearing. Its a 4x2 Super Cab.

The tallest gear avail with the 5.0 is 3.31  The eco the 3.15 just because of the low end torque.

The tallest gear in the 3.7L is 3.55

Kind of like the new 6.7 Diesel they have a 3.31 Gear as standard.

Friend that just bought a couple days ago fresh of the transport was getting 18.5 local driving with no miles and of course a few a bit harder on throttle than needed. I would expect once its got a few miles on it and easy on throttle he should get 20 back and forth to work

I am building a '66 F100 truck using the 3.5L Ecoboost and the 3.15 Gearing I expect 25-30mpg at 60mph

3.31 gearing maybe a tad quicker but not much. 3.73 the steepest gear avail with eco thats the Max tow package.  I prefer the 3.31 or 3.15 much nicer cruising around.
The new Tremor regular cab short bed will come with a 3.5L and a 4.10 Gear set. That should be interesting I am sure will absolutely dust the last Gen lightnings.

Local guy has a Ford Flex with EcoBoost and with upgraded turbo's and some tuning is putting down 600Hp @ the wheels!

All I can say is go drive a new eco with the 3.15 gear which is standard and think you will be very impressed how well it does.  If 4x4 think tallest gear is 3.31. 

Do any of you folks have any real world experience with the F-150 with eco-boost and actual performance capabilities?  What fuel economy with the supercrew cab?   Towing mileage?  I messed up and got rid of my Tundra on a whim, and now I need a truck.  My last Ford, a 2005 F-150 supercrew was a total wreck from day one, and I lost a lemon law court case on it, and I bought a Tundra.  It was a great truck, 14+towing, 18+ empty with all the comforts.  I have been a ford enthusiast all my life, but now I find myself needing a new truck without the maximum tow capability, just an occasional car/trailer one way trips.  Recommendations?   Joe-JDC.

I am putting one in a '66 F100.

I did a full comparison towing my 26' trailer and without trailer with different gear ratio's to see how they would do. friend just bought one a week ago.
Mileage really depends on what gear ratio and if 2 or 4whl drive. The trucks I tested were all 2whl drive.

the 4x2 comes with a 3.15 gear std (thats what I have in project truck) they will get 22-25mpg highway if you drive them nice. in town really depends on how much stop and go. Around here combo of city highway with a lot of that bumper to bumper highway will do 18mpg

Are you looking at a 4x4?  You may be able to pull 18-19 highway or a tad better with a 4x4 depending on gear ratio and speed. The ones with max tow package and 3.73 will get much worse mileage than the avail 3.31

When I did my trailer tow test on a very windy day with the 4x2 I was getting around 7mpg but that was extreme. With a bumper pull it will be far worse mpg than if you have goosneck. prob 3-5mpg diff. A lot of variables

I had a brand new 3v carb a few years back bolted it on my 427 Comet worked wonderful.

I think I may have a boat load of those diaphrams new in holley package if you need one.  A few minutes ago was digging thru my holley stash and saw them sitting there. Much larger than typical Holley?

Is it a 135-6?  Yup, got them.. Have had them over 30yrs
Unopened holley package if its correct.

Looking for nice ready to drop in 428 Crank for engine project. No welded on re-done junk. May consider one of the new ones like Barry sells.

Picked up a 390 that had just been rebuilt, a valve was sticking and it was a total dog. Turns out pistons are .125 in hole. Either 410 or 360 Pistons with a 390 Crank.

Thanks, I'd like to have that item number.  If Edelbrock uses glass beads on their manifolds, that's good enough for me.  Although I have been investigating some chemical dip options over the last few days...

The course beads give it kind of a sparkle~new appearance.

couple pics of my Tunnel Wedge after. Kind of poor photo's.
I have been in and out of hospital last few wks so will try to get the item number when I can.

Having a little builders regret that I did not know that the 390  has a HP limit. Initially I thought it to only be displacement. So I am thinking of using my 445 FE for my rock crawler Jeep and lining up a 428 block for the comet. Been doing some research and hooking the FE to my transfer case Is going to take some major sidestepping.  First the only adapter is to a GM trans but I have the trans and adapter all rebuilt  and ready to go. Next I have to take a walk over to the rat rod guys side of town and get a trans adapter for 500 bucks. And we are at least that far with that then radiator and exhaust will be the next obstacle to surmount.  Fortunately 390 engines came in small packages so Mustang headers should fit. Radiator is gonna be a tight squeeze not sure on that any suggestions? Thanks Jon

My brother in law has a early CJ with a 390 in it. No fit issue's at all, running some type of adaptor and a early bellhousing.

He is in process of dropping on a Fiberglass body and freshening things up a bit.
