[QUOTE=lust4speed;6229164]Way I understand it is getting close (.060") to coil bind dampens high RPM harmonics. There's some cool high speed videos showing valve springs dancing around, but the harmonics occur way over our RPM range.
I'm trying to find the best valve spring for my cam (5500 rpm max?) and am going nuts trying to figure the lift vs coil bind vs the crazy harmonics. What is the rpm range that I should be real concerned about on this. Thank you.
