This all gets to what works for the generic Mopar hot-rodder. Comp's data and the Wallace tool(s) are the easiest way for newcomers to tackle the DCR computation. (IF the static CR is well known, which is another Wallace tool.) This gets to a point in the cam specs that helps Comp.... they PUBLISH the ICA clearly in their website literature. Who else does that? So when someone such as DartFreak starts to learn this, they ask the same question as in post #230: where do you get the ICA? With no cam card in-hand, and no ICA listed in the published literature for Howards, Lunati, Crane, Hughes, Racer Brown, etc., Comp becomes the easy de-facto website to go to. No surprise then that DF looks at Comp's cams. Yeah, it may not be the best choice for other reasons, but making it easy is what Comp does better than any other MFR. Cam specs are confusing for most newcomers. Computing the ICA from LSA and advertised duration is another step of learning. AJ lays it all out in post #236, but I can see many despairing at the thought of pulling out a calculator. It needs to be in an app to get folks to adopt this thinking more. The DCR tool that I like does the ICA computation for you in a simple visual tool, including static CR computation. But then, like for the case shown by DF's situation with no PC, it is not directly available as an app for a Smartphone. (I have not tried to run it on mine but it looks like it might work.) DF, have you tried that download and running the tool that I linked, on your Smartphone?
