Considering the cam has suchcritical importance to the engines performance and life, to me it makes senseto use a cam grinder who will talk with you directly- even modify the cam grindto fit your needs even better addressing your specific environmental conditions including fuel type/quality, etc....this is what makes the difference between and engine that just has a cam change and one that really runs nice...smooth, consistent and sometimes even getting better mpg. With regards to price...the difference is nil-especially considering its cheap insurance to know exactly who is machiningsuch a critical part for your engine. And remember, advertizedlift/duration/lobe separation is just that- advertized and not the specificgrind including ramp profile that is used on the cam.
That is why I highly recommend Iskenderian & Crower & Chet Herbert& Lunati...all are family owned, been grinding cams for decades, and bothwill even re-grind your oem cam if possible- saving you even more $.
