Coil Bind on Valve Springs...........
so, i am just trying to get this straight. if my valve springs are installed at the recommended height of 1.650, and the stated coil bind for the spring is at .950, does that mean i truly have .700 of room for valve lift?(minus any margin for safety, this is of course assuming valve/piston contact is not an issue). my valve lift, after being rated with 1.65's will be .589 with this new cam, minus lash .025, (solid flat tappet), so, is my math assuming correctly that i have no problem with coil bind? i guess i would be wondering, on a pontiac engine being run to 6000rpm, what is the 'safety margin' that people use for the clearance up to the coil bind number? any and all info much appreciated, and thank you in advance folks, as usual, you all are a great help........
