No more V8 in F150?

[Diamondpilot]

I wouldn't say any one is that much above the others. The numbers can change any day. It comes down to them all being at the mercy of suppliers, but they choose and monitor the quality of the suppliers so it still falls on the manufacturer. I'm just pleased to see them issue recalls and do the right thing by fixing problems as they are found.

Any manufacturer would be foolish to try to hide it after the Toyota mess.

I think they have all learned.

You do know that the 3.5 ecoboost block has 6 bolt mains and it supports the forged crankshaft with a girdle...right?

Was just thinking, is the Ecoboost OHV or DOHC ? four bolt mains, IMHO, only make sense on OHV V engines to add structural rigidity to the block, because OHV V engines have this hole in the bottom of the Vee to accomodate the camshaft. Ecoboost probably has a much stiffer block due to the absence of the camshaft bore in this key area.

Four and six bolt main bearing caps are used to seat and support the crank in high stress situations. The higher loads the engine is built to be rated for, the more support the crank needs to remain true. Many SOHC/DOHC engines (V8 and V6) still have a "cam bore" through the block, but rather than a camshaft, it has what is called an intermediate jackshaft. This is basically a shaft that runs from a timing chain off the crank, then uses two more timing chains to drive cams in the heads. Generally the head on the driver's side is ran from the front, and the passenger's side head is ran off the back of the engine. This is how the 3.5L ecoboost is built.

The ecoboost has more main bearing surface area to support the crank than any of the gas V8s ever produced, which is pretty much the main reason the ecoboost is rated to take more load down the road than any of the V8s. To have the rigidity and support for these larger-than-typically-used-on-an-engine-of-this-size bearings, engineers decided on 6 bolt main caps. Longevity under load was their goal.

Aluminium blocks are also a factor that weighs in: I think its BMW that has an engine which head bolts are bolted all the way down to the crank bearing area, to save some meat in the area inbetween.

===edit: i think Ford is doing what BMW is doing for more than 10 years now:
Engine of the Month - Ford 2.7-Liter Twin Turbo EcoBoost V-6

On inline engines i have never seen more than two bolt mains... Thats also because there is more room to put larger diameter studs in the block, and still have enough meat to thread them into. If you look at, e.g. LS1 (??) engines, they have a cross hole to turn two lateral bolts into the bearing cap, to tie the bottom end together like one rigid part. I have never seen such thing on heavy duty industrial engines...

Well, well, looks like the 5.0 is coming back for 2018. Yeah, little V6 just doesn't cut it, for real truck work.

Coming back for 2018? It never left. Although most sales are for the V6 engines now, and some of the V6 versions are more powerful than the V8, but there are still many V8 sales to go around.

I'm waiting on the 2018 model order bank to open up and will go with the 3.5 this time, but only because i don't keep vehicles more then 4-5 years and am not overly concerned about the complexity of the ecoboost engines. Otherwise I'd go with the 5L again. I think Dearborn will start the 18's mid July. Kentucky a little later.

NEW ENGINE OPTIONS

Based on your need, the 2018 F-150 provides more engine alternatives all paired with a 10-speed transmission to deliver improved acceleration and performance.

- All-new standard 3.3L Ti-VCT V6 – 290 HP/265 lb.-ft./rpm
- 2.7L EcoBoost® - 325 HP/400 lb.-ft./rpm
- 5.0L Ti-VCT V8 - 385 HP/397 lb.-ft./rpm
- 3.5L EcoBoost - 375 HP/470 lb.-ft./rpm
- High-output 3.5L EcoBoost (on F-150 Raptor) - 450 HP/510 lb.-ft./rpm

Also look for yet another powerful new option… with a new 3.0L Power Stroke® Diesel engine. Coming in Spring 2018.

FYI, Dearborn (DTP) and Kansas City (KCAP) build the F150. The Super Duty is built in Kentucky (KTP).

Right, i goofed. I know the 150 is build at both Plants. I may be wrong, but since i ordered my 2012 Plat with a 6.5 foot box, which was build in Dearborn, all 6.5 foot models are now build at KCAP. Would you know if that's accurate?
