I need schooling - old vs. new engines

My gen III is all motor and makes somewhere between 650 and 700 HP. It has the most radical race cam Comp makes for that motor and it doesn't really idle that lumpy.
I don't have my hands on the cam specs right now but I think you are spot on with the LSA at 114. I do idle it quite high for racing purposes and there is no VVT on this motor.
Take a 5.7, put Eagle heads on it Raise compression to 13.5:1 with custom pistons, put a cam and a stroker crank in it and this is the output it gives without power adders.
I also have a decent hi rise racing intake and a Holley sniper 4500 EFI on it.

Very nice. Unported heads, correct?

I wonder what a 5.9 with the same formula would do.

Stock heads
Stroker crank
High compression pistons
Big cam
Single plane intake

Hmm....I'm no motor wizard, but I bet it isn't anywhere close to 650+ hp.
