3G Hemi vs LSx vs Ford Mod Motor - which is the 'best'? And which to put in mopar?

I know that price is always an issue, but seems to me the question was more of a technical question and I read it as more of a "regardless of price" kind of a question, i.e. which motor is the best design.

FWIW my opinion is, the Coyote is probably the most advanced of the three. Hard to beat multiple cams and the advantages that cam phasing adds to that, on top of 4 valves per cylinder (funny, it's about the heads again). Heck, as I understand it, Ford even engineered the oil system for horsepower. At the same time, the physical size of the motor is a real detractor, and the high rpm nature plus the lack of cubic inches makes it feel a little "mundane" around town (at least in my experience while riding in a buddy's '13 GT). Just didn't seem like it had much low end torque. My brother just got done building a trick '55 Vicki with a crate Coyote for a guy and will be taking to all kinds of shows this summer, and he doesn't drive anything softly, so I should have another comparison by the end of the summer.

I think the 3G Hemi heads give that motor a technical advantage over the LS, but it loses out on the size.

Only advantage the LS has (if you ignore costs) is it is smaller and easier to fit. If I were to move over to an E36 BMW, I would probably look really hard at putting an LS motor in it.

I wouldn't put an LS in a Mopar. Call me a purist if you will, but I don't have issues with other parts (R154 transmission, Supra rear brakes, BMW E30 Sport Seats, etc.), but the motor is a non-negotiable.

On a side note, I don't believe Mopar sat on their LA laurels for years while GM developed the LS. The Viper V10 is a direct evolution of the LA and now makes 640 hp and 600 ft/lbs, I just wish Mopar had split the line and built a V8 version, too. A 6.7L V8 version would have made over 512 hp and 480 ft/lbs, right in line with the LS7 (505/470). But they didn't and it makes a certain amount of sense since Mopar didn't have a car to put it in, and it would have been a competitor to the Viper if they had.

Biggest problem the 3G Hemi has is in the ECU. Chrysler has always been too tight with their code, so everything has taken so much longer to develop from the aftermarket.
