Forging the 5.0???

[NeoTokyo]

Shoot anyone can send a spec sheet in to any of the rod and piston manufacturers and get a set of stock sized forged pistons and rods for a decent price.

Oh and of course you dont have to leave the pistons and rods at the stock specs.

Ford also mentioned how important it was that they have a rod/piston combo that only weighed in at 1 kilo.

So of course trying to stick with that weight or go lighter will result in a change of the design.

This 5.0 article talks about it.
2011 Mustang GT Coyote Engine - 5.0 Mustang & Fast Fords

the V-angle, bore spacing, and deck height all had to stay the same, because the execs wanted to save money by producing this engine on the same line as all other modular engines(4.6/5.4/6.8). by keeping all of these dimensions the same, the block can be machined by the same machines that ford is already using, they don't need to spend cash on new machinery. technically, this also makes the coyote a modular motor, since the "modular" name refers to the fact that multiple engines can be produced on the same line.
besides these dimensions though, the block is 100% clean sheet. the oiling system and the cooling system are completely different from the 1st gen of mod motors. technically, i guess the coyote is a 4.6l-clean sheet hybrid of sorts, lol.

Term "Modular" had nothing to do with the interchanability of major components like heads?

If Ford decides at some point to incorporate the PTWA spray bore technology into the Coyote design they could theoretically increase the bore size by using a thinner coating on the cylinder walls than is required for the current pressed-in cylinder sleeves. I doubt they would do that since they chose not to on the GT500 aluminum block but it could be possible. Once the technology becomes more commonplace it might even be possible for to remanufacture older blocks by replacing the sleeves with sprayed on liners. Block strength could be an issue but it might be possible to increase the bore size by again using a thinner coating than the the original sleeve thickness. Probably not practical for a high mileage street application but it might be a way to increase displacement for a racing application.

well, yes and no. while the major components are interchangeable - or 'modular' - that's simply a by product of the different blocks being machined on the same line. 4.6l heads will bolt onto a 5.4l because the 5.4l had to have the same dimensions(deck height aside) to be machined on the same line as the 4.6l.
also, by keeping the 4.6l, 5.4l, and 6.8l virtually identicle aside from the deck height and # of cylinders saved a LOT of money, vs designing 3 different engines. the only problem is that all 3 engines suffer from the same limitations, which is why components like heads won't fit the coyote(different cooling passage arrangement for improved performance and the like). so, essentially, this makes the coyote the 2nd generation of the modular line.

I think it's on Modularfords.com, but I've seen pics of Livernois' new pistons. Look nice coupled with some Manley rods, voila ready for boost.

Nice Rick,

I'm on too many forums to keep it straight. Good work!

When you stroke an engine, you are just trading RPM for displacement anyways. The lack of a stroking option really won't limit power at all, as you will be able to push the revs more on the smaller motor.

thats entirely wrong. cubic inches = horsepower.

lol don't get so scientific with you're answer there!! :lol1:

it could be argued that headflow = horsepower. he did have a point about stroking limiting RPM's because of piston speeds.
