I'm wanting to know what rpm range m i looking at in six gear going 75 on both of these gears???

i have heard you need gears for a cam for better results, but i got no experience in this, and dont want to regret my purchase

you don't need gears for a cam. although if you have an auto, you should get a converter, depending on cam size.

Well I was told when I changed my gears that the 3.73 worked best for the autos and 4.11 were for manuals....
