My 422 smallblock build
You may have to try and explain it to me in layman’s terms because I do not speak much “camese”. How would putting it in at 106 be better than putting it in at 104? More power in the upper rpms? Better idle quality? I don’t understand.
You need to find and read the entire article where Godbold outlines why Comp can grind everything on a de facto LSA and then advocate for installing everything 4 degrees advanced from the ICL and then on the other hand, do just the opposite when you talk about a performance engine. I hardly consider your build a milquetoast build. I consider it a performance build.
In that case, you would center the overlap triangle for best performance. That is overall power output, across the entire RPM range.
I ran your cam numbers, and to center the overlap triangle you need to install your cam on a 106 ICL, if you want maximum performance.
If you are trying to crutch some part of the build (poor headers, wrong converter, not enough gear etc.) then you want to advance the cam. It damn sure isn’t for better performance.
I mean...think about it...how is every cam always installed 4 degrees ahead? It doesn’t make sense, especially if you have done your due diligence in putting your engine/chassis package together. It’s like the de facto 110 LSA. It’s a best acceptable LSA for stuff that isn’t well thought out.
BTW...with the mgispeedware.com cam program, you can easily calculate how much actual advance is ground into your cam, and it is NOT 4 degrees. It’s only 2 degrees. So why install it 4 degrees ahead?
