5.0L Coyote Retrofit in 2005-2009
Anyways, I still think its an excellent engine going forward and years down the road will probably be a common engine swap - at some point the economics of installing the 5.0 will be negligible. The 4.6 3v is a good engine but its little more than a side note rendered obsolete by the new engine (the 4.6 3v is neither backwards or forwards compatible). After availability becomes a non-issue and aftermarket parts become common place why stick with the 4.6 3v when going with a 5.0 4v will - pound for pound - produce better results.
The only problem with the 5.0 I see is that Ford, doing SNAFU, is that like the 4.6 3v they might abandon the architecture in a few years which IMO is a bad mistake, one of the endearing things about the Brand-X guys is that they dont change engine architectures on a whim. Ford would be smart with the 5.0 to make parts commonality over the life of the engine a major consideration so that the aftermarket and the faithful don't have to reinvent themselves every coupla years.

The Three-Valve short-block is extremely similar to the modular engines in the '96-'04 models, and the chain setup seems to be a direct carryover, as well. But the camshafts, cylinder heads, and intake manifold are vastly different...
Groh used a '97 Cobra engine block, as they are supposed to be nearly identical to the Three-Valve engines, though a bit lighter and stronger. They were close enough, albeit there were a few minor issues with the motor mounts. JPC is working on motor mounts to retrofit the earlier modular blocks into your '05-up Stang...

Went to Ford Racing. 5.0 crate engine is 6999 dressed minus AC and Alternator. Bell housing bolt pattern is common to the 4.6 as is the engine mounts. Looks like it would be a drop in exchange for a 2005-2009 GT. It would require that the PCM and harness be added of course and perhaps a cooling system and exhaust upgrade as well. I would imagine a DIY guy could drop a 5.0 into their GT with the same transmission for 10K or so. Now then will that engine pass 50 state smog?
The 4.6 3v stuff isn't forwards compatible with the 5.0, but it is definitely backwards compatible with older modular shortblocks (2v and 4v)
Chevy V8 stuff is no longer backwards compatible. LS engine pieces aren't compatible with LT engines and LT & LS engine parts aren't compatible with the original Chevy small block. The Ford Modular engines have been around since about 1991 so the architecture has been around for around 20 years. During that time, GM went from the original Chevy Small block, to LT, then to LS.

As for GM I know the OSB and LT stuff aren't compatible with the LS engines, but I believe heads are interchangable as long as the correct intake is used (the LS1 engines used a cathederal port for better valvetrain geometry vs. a more conventional rectangle).
In any event, my opinion still stands, Ford needs to let the 5.0 mature so that the aftermarket will embrace the engine like well the orginal 5.0 .
I would be curious to see how the saleen 302 goes against the new 5.0, I think lots of people would be surprised. All this talk of efficiency and the 5.0 having so much more potential, I'm still confused as to what that means.
Stroker engine would be great for the street, though.
Stroking an engine makes it more undersquare, meaning piston speeds will be higher and loads on the rods and wristpins will increase. This means the engine becomes a liability during sustained high-RPM use (moreso than normal, lol).

Put one way, the coyote heads have about 100 more HP potential over the 3 valve heads stock to stock. The only place the coyote falls down compared to the 4.6 3v is the VVT system. The coyote uses a cam torque actuated system as opposed to an oil pressure actuated system. The former doesn't require a high pressure oil pump to actuate the cams but suffers from high rpm instability while the latter is better at high rpm control. Ultimately though on a max effort engine, chances are that the VVT system will be locked out anyways, so its moot.
Its all in the cylinderheads, the coyote heads outflow the GT500 heads by about 4% IIRC not to mention a much improved combustion chamber over the 3 valve head (less detonation prone which means more ignition timing or more boost).

And 4% better flow is not that big. So far, I haven't seen too many projects where the mods were restricted by the lack of flow of the heads. I'm not disputing the new 4v heads in the 5.0 are not the best ford has come out with yet, but to get 100hp over the 3v heads? ? Not sure I follow how that could happen
I think that started due to the price of Ford's previus 400+ hp mod motors (4.6/5.4 SC - Cammer - 5.4 Cobra R, et al) - However I figured the 5.0 wouldn't come in anywhere near that simply because Ford either wasn't going to add a 7k mark up to its entry level V8 (and lose its *** to the competition) nor where they going to take a hit and lose money on every GT that goes out the door.

I see the 4.6 3v more or less the 351 Cleveland of its time (well sorta), going forward I think the 2v and 4v engines (pre coyote) wil be the ones that show up more often than not, but given the accessibility of the coyote's performance capability going forward and unless Ford reinvent's the wheel in the next coupla years, I suspect the coyote will become the MOD version of the windsor.

In the end, with either motor it looks like 500hp is the (easy) cap (pretty easy to attain) for both the 4.6 & 5.0. But more than that requires better internals.
Therefore, what did 4 the cam/4V really achieve over 2 cam/3V (excluding displacement)?
The emission standards must meet the car or the engine standards depending on the latest year for either. So an engine from a 2011 will need to meet 2011 standards even if it were to be placed in a 2005 car. And your right, the first smog check after the change would be to a referee.
better numbers straight from the factory so they can advertise it and sell more cars
