Which engine would a Ford tech choose for an F150

ALL 2.7s have external water pump.

I've driven the 3.5 EB, plenty of power! I hate the sound of the EB in a truck, doesn't come close to a V8. Of course not everyone buys a vehicle for sound.

Ask a ford tech. lol You guys ever watch Joe Diesel on youtube? He loves the 6.0 you know why? Because it keeps him employed. Are they telling you guys which is more dependable or which one keeps them busy at work?

Expedition have a timing chain water pump also?

Rented a new one in a van once. it had 9 miles on it when I picked it up. On the way home from Canada
I stopped to fuel up and check the oil- I could not believe it was no V8- of course I didn't ask- great engine!

I have one in my van sitting under the carport. Great engine.

I have a buddy who is a Ford Service writer in PA, we had the EB conversation a few times. He's with the guys in the video and would take the 5.0 over the EB engine as well. Talking with techs are guys who deal with these engines all day long is a good way to learn how reliable they are.


It has plenty of power, gas mileage OTOH is not so great.

Forgot about that - no, it's based on the F150 so it gets the external water pump. Wish I could go back and edit my previous post.

I want a 429 385 in my f100

I would imagine in case the WP went south(and caught in time before it wipes the motor out) on a longitudinally-mounted EB 3.5, it would be an easier task to leave the engine mounted on the frame than it is to drop the subframe on the FWD models that use that engine(Explorer/Edge/Taurus SHO)? How difficult of a task is to replace the water pump once all the belt driven accessories are off the front?

As for an engine, 351 on the older square bodied trucks, 5.4L mod motor on the 1996-2009 trucks, 3.5L EB for the newest ones.

You'd get some really impressive area under the curve and driveability upgrades on the EcoBoost even with an 87 octane tune.

Like PBM above...when I read the title I thought...thats an easy one...4.9 with 5-speed OD.

Pretty much nothing unusual about the car design, except that it is internal to the timing cover. So when it goes, it unloads engine coolant into the crankcase with little or no warning.

My only guess is that because the engine is transverse, they attempted to save space in any way possible. There is one individual who claims that he was told by a Ford engineer that they had designed some sort of weep channel to allow the pump to exhaust its overflow out of the engine. Obviously this does not actually work, assuming it is true.

I'm not a huge fan of timing chain driven water pumps in general, because even external to the engine, a pump seizure means your timing assembly is destroyed.


Thank you for the further details.

I'm not a ford tech, but if I had $35K laying around to blow on a truck, It would be a FISO with a 2.7 EB. Single cab, long bed. Would handle 100% of my truck needs.

Plus it's really cool that such a small engine can do so much work!

I'm sure they aren't allowed to say that on video, but it's probably what they are thinking.


Water pump inside the engine? Next......... I'd go with the 5.0 too.


How is this any different than a timing belt driven water pump on an interference engine?

I was asking: Water pump inside the engine? It sounded odd, I figured Ford was smarter than that. I'd pass on a timing belt driven water pump on an interference engine too.

I'd take the 3.5 over the 5.0. Torque speaks to me. The 5.0 coyote is a solid engine and I'm waiting for the twin turbo variant that will make me run around the house naked

I would have a tough decision if it was between the 5.0 and the 2.7. Either one in a regular cab long bed would make me very happy

I don't think they can turbo the 5.0. The 3.5EB weighs about the same as the 5.0, which surprised me. But I guess in order to keep the bottom end in one piece, it's gotta be strong (which usually means heft). Ok, they can turbo it, but I doubt they can approach the same boost levels and hp/liter, and have it hold together. Just a swag on my part.

The Coyote can handle boost, that isn't a problem at all. The block has 6 bolt mains and it is a deep skirt block.

If we were talking -14 trucks I would take a 6.2L because the only one of those I would consider would be a Raptor. On the newer ones I would try to get a 5.0, a lot less issues with them on a day to day basis. However the new 3.5L that has both direct and port fuel injection is pretty awesome. A V6 just does not sound right with exhaust. I took video of a new Raptor at work with some kind of exhaust and it sounds absolutely terrible, like I would be embarrassed to drive it bad.

Borla has a kit with true duals and new turbos that is supposed to be good for upto 175 HP on a 3.5EB. you have to run a catless down pipe to get that much, but even if it only adds 125 with cats... that is still pretty strong...

I have seen the kit, it is pretty awesome. Not legal in California that I have seen yet, even with cats. Borla is one of those companies that can do no wrong IMHO. I have their ATAK catback on my 2014 Mustang, very loud and raspy with lots of popping on decel.

My good friend has the 2.7EB and it's smoother, better sounding as it revs higher, and even faster! I do like the EB engines. I simply do not like the sound of the big V6.



Precisely why we did not consider any V6's when we bought our last pickup. I think my good friend's Egoboost 2.7 PU is amazingly powerful but the gasping and wheezing sounds from under the hood are not for me...

1. Because the pump is inside of the engine, there have been many incidents in which the coolant simply came out of the pump into the engine, and wiped out the engine. With an external pump, that coolant is going out onto the ground, and nowhere else. Many people who had engine failure had such because they were unaware of the coolant leak. It was contained in the engine, or happened so fast that there was never a chance.

2. Timing belt driven water pumps can definitely be disastrous when a failure occurs. Timing chain water pumps are a somewhat worse because a pump seizure usually results in complete shattering of the timing chains and sometimes the gears as well. With a belt, you just replace the belt and carry on with non-interference. With interference, you can many times ditch the head and get a new belt in there. With interference/chains, you are in a world broken parts, including the head.
