Exclamation Boss 302 Engine specs vs standard 5.0 coyote engine specs

Hey folks,

What are the differences (internal and external) to the Boss 302 engine and a standard 5.0 like what's in my 300A spec car?

I'm pretty sure it's the intake, cams, programming, etc... Anything else? I like the idea of swapping a Boss intake onto my car but wanted to know if the cams are different as well and what kind of power you can get with just the intake and tune vs a full Boss engine and tune.

Thanks for any help!

Bullet points from the press release are:

* Revised composite intake system with shorter runners, inspired by Daytona Prototype racing engines, for high-rpm breathing
* Forged aluminum pistons and upgraded sinter-forged connecting rods for improved strength, needed for the higher combustion pressures and engine speeds
* New high-strength aluminum-alloy cylinder heads with fully CNC-machined ports and chambers for exceptional high-rpm airflow without sacrificing low-speed torque
* Lightened valvetrain components to provide excellent dynamic performance up to speeds well above the engine redline
* Sodium-filled exhaust valves for improved heat dissipation
* Race-specification crankshaft main and rod bearings for higher load capability and improved high-speed durability
* 5W50 full-synthetic oil with engine oil cooler for improved oil pressure and longer-lasting lubrication during extreme racing conditions
* Revised oil pan baffling for improved oil control under racing conditions and during cornering loads greater than 1.0 g

The intake manifold is attributed for a lot of the power gain from what I read in the book, but all the supporting upgrades do a lot for durability I'm sure.
