the 06 taurus only had one engine available that was the vulcan... as for duratec compared to vulcan. i would say the vulcan is pretty bullet proof but has a few key issues with it (cam syncro, cooling system corrosion, etc.) the engine is a bit lower on power but get a bit better mileage than the duratec. the Duratec is also a good engine though, plenty of power and they can go for a very long time with regular maintenance. though the duratec is a larger engine and that makes it harder to work on. I love my duratec and would have a very hard time going back to a vulcan.

They have the same displacement (182 cubic inches, although some sources quote the 'tec as 181) It's really just the heads that are larger on the 'tec. Also, the Vulcan is all-iron whereas the Duratec is all-aluminum so it weighs less.

Both are good engines. Like previously stated, you really dont have an option for 06, except for the flex fuel version of the vulcan. In 07, you dont even have that. The 3.0 tecs were last put in tauri in 05, but were used in the ford 500 for 3 yrs. (05-07).

the 8th digit of the Vin is the engine code. U for Vulcan and I believe S for Duratec.

The tecs get the same milage as the vulcans thanks to the dohc design. :)

I'm kind spoiled having the tec engines.

When Fusion time comes around, it'll be a tough decision between the 2.5 175 hp 4 cyl vs the DOHC 240 hp 3.0, especially with gas prices!!

There's a long debate about the OHV 3.0

I think they could have addressed much more than the cam issue. Like this:

3.8 Essex

200 HP
230 TQ

52.63 HP/L
60.52 TQ/L

3.0 Vulcan

145 HP
170 TQ

48.33 HP/L
58.00 TQ/L

The Vulcan makes 4 less HP per litre and 2 less lb.ft as well. If the Vulcan had comparable power in terms of displacement to the Essex, it would have made around 160 HP and 182 lb.ft. GM's 60 Degree made that (more actually) at 3.1, so why couldn't Ford? The engine should have received a decent redesign like the Essex got. It didn't though and they kept it at 4-banger output levels. The Buick 3.8 made comparable power levels to an Essex, too.

We should have a way better engine than we do. They should have made the heads a little thicker while they were at it. This engine was neglected. The Vulcan didn't even compete with domestic offerings:

Chrysler OHV 3.3 V6:

160 HP
203 lb.ft

GM 60 Degree 3.1:

160 HP
185 lb·ft

Ford Vulcan 3.0

144 HP
174 lb.ft

It gets even worse for the 4th gen. I'm still incredibly amazed as to why they even tried putting it in the windstar, the MPG rating was worse than an engine that displaced another .8 litres and made a ton more power too.

I have some ideas as to why they screwed up the engines in the 3rd gen so badly:

Ford SHO V8 engine

It made 235 hp and 230 lb·ft, just 35 more HP than the 3.8 would have made. It matches the lf.ft rating and does it at a lower RPM range. I think this is a big reason for them not continuing the Essex engine in the Taurus, it would have made the SHO seem worthless.

The head gasket issues probably didn't help with the situation.

The 3rd gen SHO should have never been. Not to offend anyone, but it really shouldn't. They should have just stuck one of their then current mustang engines, the 3.8 Essex or the 4.6 Modular. It would have been way more fun in my opinion to be able to go and buy add ons that are made for Mustang owners. If they did that then we could easily piggy back off the after market for the Mustang. A supercharged, 3.8 Taurus? Is it better than a SHO V8? I would guess that it is.
^^ that's what I think about the Vulcan.
