Hi guys!
Do you know if there is someone who produce more performant cams for 7AFE engine? the only site I found with aftermarket cams is Import performance which sells TopLine cams. Who know about this manufacter?is it good? Also, does anyone know how to get regrinds, valves and springs for better performance and which are stronger than stock? Thanks

Here are a couple of other sites that I found that might help with the explanation on camshafts:
http://www.drschrick.de/english/index.php http://www.arrowprecision.co.uk/ Basically, an increase in the degree of the cam has the effect of opening the valve for a longer time thus this is the duration that the valve is open. If the valve is open longer then this allows more air/fuel mix into the cyclinder (suck cycle) and more gases let out (blow cycle). Something to bear in mind is that in order for the cams to meet there full potential other mods need to be done: air, fuel, ignition and exhaust upgrades. (One example, no point in the the exhaust valve opening longer if the header is restricting/can't cope with the extra gases being forced out).
