[GT500-07]

Cutbacks, by Ford, on their large displacement V8 truck engine known as the Boss program, could free up the name for the 5.0-liter engine in the 2010 Mustang.

These recent articles are confusing and I'm not sure who has the right story. As I understand it at the moment....

Formerly there was a new Ford V8 coming out called a "Hurricane". After hurricane Katrina hit, the politically-correct police decided that the Hurricane name be changed to Boss. Apparently there were two Boss (formerly Hurricane) engines in the works, one being a 6.2 and the other a 5.0. Now, due to the Arabs and commodity speculators driving the price of gas to the extremes, Ford has decided to "pause" the introduction of the new F-150, and also the introduction of the now-Boss 6.2. But, apparently the Boss 5.0 green light is still on.

Why the heck they didn't just call it a Boss to begin with is beyond me.

They're actually confusing several things...

BOSS is a branding program having nothing to do with a specific engine (really). In a Ford media release about a year and half ago they eluded to this. The intent was to use the revered BOSS name to do what DCX did with the Hemi redux but taking it further to a broad branding program.

The Hurricane-turned-Boss was to be 6.2 and 5.8 (not 5.0). The 5.0 BOSS has always been in the context of a Mustang and is a revised modular (slightly longer cylinder sleeves, slightly larger bore, block strengthening) to get to 5.0L. It's builf off the low-deck alloy modular (like the 4.6GT) but in DOHC (like the '03-'04 Cobras) but in alloy (like the '99/'01 Cobras) but beffier (like the low-deck Aluminator used in drifting). It is unrelated to the H/Boss sharing essentially no parts. It's also not to be confused with the 5.4 modular with is a hi-deck version of the modular (room for longer stroke) distinct from the 4.6 (low-deck). So, you could say the revised 5.0 (BOSS 5.0, we hope ) is like a modified '99/'01 DOHC mod with all that been learned since and accommodating 5.0L displacement.

I don't believe for one second that a BOSS 5.0 mustang is in anyway dependent on Ford cancelling the H/Boss for the F-150/Expedition. BOSS was (and likely still is)a branding program that would potentially apply to many vehicles. If Ford decides not to brand that way it will, imo, be because EcoBoost may be better politically focussed these days. Even than, I think the Mustang will be BOSS branded regardless of whether H/Boss motor is branded BOSS or not in the trucks.

In summary, there are several different engine families any of which have, are, or may become BOSS-branded (least likely for family 1/1A):

Family-1:
"vanilla-modular"
Eamples:
-- low-deck versions (alloy): 3V SOHC 4.6 M-GT, 4V DOHC 4.6 '99'/'01 Cobras
-- low-deck versions (iron): 2V SOHC 4.6 CVs; 4V DOHC 4.6 '03/'04 Cobras
-- hi-deck versions (alloy): 4V DOHC F-GT
-- hi-deck versions (iron): 3V SOHC 5.4 Lightnings, 4V DOHC 5.4 GT500

Family-1A
"revised modular" (beefed block...)
Examples:
-- low-deck version (alloy): 4V DOHC 4.6 Aluminator (FRP aftermarket only, both short- and long-block assemblies, plug-replaces '03/'04 Cobra's iron block, uesd in pro drifting, excelent 4.6 build-up base, supports at least 750HP)

Family-1B "revised modular" (beefed block, longer sleeves...)
Examples:
-- low-deck version (alloy): 4V DOHC 5.0 '10MY BOSS Mustang (anticipated)
-- low-deck version (iron): none yet ...likely candidate to replace 4.6s in the trucks: F-150, explorer America, Expedition...

Family-2: Hurricane/Boss -- clean-sheet large "cammer" design unrelated to anything above
Eamples:
-- (iron): 2V SOHC 6.2 future F-series (possibly now just SuperDuty, was to be branded BOSS), 5.8 SOHC was to repl 4.6 in trucks (shelved??)
-- (alloy): purely speculation for BOSS 351 (5.8) and BOSS 429 (7.0L B/S'd 6.2 per Roush/Bowles E85 mule), DOHC version rumored to bee seen in-development but with no plan to produce

Of course there's also the existing (vintage and current-revised) BOSS-branded motors
Examples:
-- low-deck SBF vintage BOSS-302
-- low-deck current-revisedFRP BOSS-302 and BOSS-branded derivatives
-- hi-deck SBF vintage BOSS-351
-- hi-deck SBF current-revised FRP BOSS-351 and BOSS-branded derivatives (coming this fall??)
-- 385-series BOSS-429 (unrelated to the FE-series 427 BBFs, etc.)

The above is why there's a lot of confusion out there, imo <lol> Vintage BOSSes, redux 'vintage' BOSS crates, coming 'branded' BOSSes (H/Boss in trucks), coming revised-modular BOSS 5.0 Mustang, potentially more.

It gets further confused when Ford has Galpin Motorsports do an S197 BOSS-302 that uses the revised-vintage BOSS FRP crate 302 for the 2006 SEMA show! And of course there's the BOSSes out there by the Shinoda group too which are another 'branch' of the BOSS family tree created by immaculate conception

Oh, and let's not forget the Aussie BOSSes too ... <sheesh!> It's enough to thoroughly confuse even the sincerely-interestred casual observer. Oh, wait! That's exactly what a *branding* program is *designed* to do!! (Is the DCX "Hemi" either a real hemi or a meaningful modern engine worthy of the name?) No wonder then ...and it's all good, imo, as long as Ford puts the right *good* pieces in the right cars ...and does it before I'm too old to get my license renewed! ;-)

Correct,

The Boss engine PROGRAM and the Boss MUSTANG are two different animals. My bet is that you will see a Boss Mustang soon.

Robert,

I notice your signature says you are getting a Terlingua.

Are you still getting the KR?

...the sooner the better

MY sources that are real close to alot of people at ford that work in the mustang program say if there isnt a boss mustang in 2010 dont ever count on there ever being one.

2010 = No BOSS.

[SpeedRacer]

I agree with Pawn. We work with Ford and we're hearing no Boss.

No Boss but an aluminum block 5 litre & a 6.2 litre engine for the Mustang.

[falcongtho3]

The soon-to-come 5.0 DOHC engine for the Mustang is currently going by the name Coyote. The Boss name has been tagged to the former Hurricane (6.2) engine which was scheduled to debut in the 2010 H-D F-150, and later find its way into various Mustangs .
The Kar Kraft engine that is being tauted as an Aussie Boss (260/290/302 kW) is not an Aussie engine from what I understand. Which is really strange since the Aussie Boss engines are built in North America and then shipped there for final assembly, and use in their Falcon sedans and Ute's.

The new 6.2 is going to be installed in the Superduty trucks.
