Related question. I see many guys on this forum struggle to get over 500 rwhp in an NA engine. The crank power of such an engine should be around 575 or so. That is with the 6.2 liter which I believe is 376 cubic inches.
So again why are the chevy engines struggling to get there and ford can put out a 550 hp engine right out of the factory. You know that car will be street driveable so how do they do it. 
Real answers please no silly things like "duh, well Ford engines are just better."

I get the weight thing but so is the power. I also get as 'Lowdown said that RPM capability is a big thing. An engine that can breath higher and run higher RPM will all other things equal make more power.
I have been saying to my Camaro friends for awhile I want my LS3 modified to breath better and rev higher. That aside why doesn't GM do it, why don't more modders do it to the LS3?
The higher RPM capability built into the LS7 is one reason that engine is so beloved, why don't they make that engine put out more HP in the Z28 it always seems they leave us just wanting and having to catch up to the Ford guys with our own mods.
