I would like to understand how to pick a cam, and how all the other factors affect selecting the right cam. I'm not an idiot but just reading what I can find here it's like the harder I try to get it the less it all makes sense.
Is there a good book, website, or tutorial I can use to get a handle on this?
Generally look at many builds as possible that give engine with dyno and or track time and see how mainly cid heads and cam effect performance, as well as cr, intake and exhaust systems etc.
Keeps notes of specs and results you'll start to see trends.
Richard Holdener has lot of dyno vids
Here a link a search of his cam shootout mainly non dodge but still help you learn.
