Obviously we are not going to agree here. I'll keep doing it my way no one is stopping you from doing it your way. Just trying to let the OP understand what cam grinders want to know before grinding a custom cam. I am not an off the shelf cam kind of guy.


For reference, here is a order form from Elgin Cams. Please feel free to see what info Dema asks for: http://www.elgincams.com/order.pdf

Here is a link to Bullet Racing cams order form: http://www.bulletcams.com/RecForm/index.html

Tick Performance cam work sheet: https://www.tickperformance.com/cont...mworksheet.pdf

Unfortunately I can't provide a direct link to Dougherty Racing Cams order form but it can be found by clicking here http://www.drcamshafts.com/ and then order form.



I could go on and on. But there must be some reason that every one of them wants to know a LOT more info than just target RPM range and heads, including ALL of the things I mentioned and more. I could only imagine the response you would get from a custom cam guy if you were to say "Here are my heads, here is the RPM I want to turn, grind me a cam and I'll figure out the intake and headers to go with it."


To add to that, you should see what most converter MFG's want to see as well. Most are ok with knowing peak TQ and vehicle weight along with power adder if any.
