When I ran our CC 410 in my car, it ran best shifted around 6000-6500rpm! On dyno it made peak at 5400rpm!!
Looking at the graph's, both my engine and Louis' engine only dropped 12HP from peak to 500rpm after!
Curious, what did the hp peak at?
And I've seen in a sb mopar that tight lobe centers actually SPREAD the power out better and wide lobe centers make the tq curve more peaky.
Very interesting. That's certainly out the realm of common knowledge and my empirical experience, but I never claimed to know it all. Did these engines have aftermarket and/or ported heads or were they stock cast iron? I firmly believe that port shape has noticable effect along with volume and flow on true power output.
If you have decent airflow and a ton of port speed you can actually make an engine perform better than the typical scenario.
