Agreed.
I understand this concept of matching a top end to a specific cubic inch displacement, it seems very theoretical to me though.
I could understand how it might be applicable in perhaps an extreme rpm formula 1 engine at 20,000RPM where everyrting is voodoo to guys like me.
Not so much for a pushrod V8 that won't even see 8000RPM in either the bigger or smaller configuration.
In practice I'm not aware of nor have I ever witnessed any situation where increasing to a larger displacement bottom end configuration was detrimental to horsepower output.
If you know that this can indeed be the case, Would it be possible to provide me with an example?
