so i have to send them one? my "old one" instead just buy one, your right for like 10 bucks and ship them that...but do they make it out of the old one? i'm so flippin lost people[&:]

 

yes what they do is when they receive your old cam they clean it and inspect it for any things that would cause problems then what they do is regrind the lobes and reshape them to change up your power curve of the motor. Now if you go with a stage2 or stage3 regrind they actually weld onto the lobes and regrind them to make them bigger/taller/fatter and reshape them as well. The only reason you can only get regrinds is because the motors are popular enough like the d16z6's d16y8's DOHC's etc and not as much of a demand for them so its cheaper and easier for them and the customer to just get a regrind. Hope i didnt lose you in that

 

now i truly understand what your talking about thanks bro
