I have a couple of cam questions. After breaking in a cam and running about 1000 miles how close should you be to the manufactures lift lobe lift number? I know there is some wear during break in but what would be consider normal or should the measure I get be exactly what the card says? How much variation in lobe lift should you expect to see from lobe to lobe on a camshaft after it is broke in? I am running an Isky Z60 solid flat tappet cam that is supposed to have a lobe lift of .365". I just finished checking all lobes using the lifters for the cam and pushrod with a .0001 digital dial indicater and got readings from a high of .3620 to a low of .3565. Most of the lobes(11) were between .3590-.3600 and I saw no unusal wear on the lifter bottoms that would point to a bad break in. Is the variation I am seeing something to worry about or is it normal??

'Bow';

Was the dial indicator placed in the same plane as the lifter? I know this is hard with the heads on - but there are special extensions (I machined my own) that allow you to use the pushrod hole, so you get good readings with the heads installed. If not the readings you give may be caused by this missalignment.
You also need a good flat area of the lifter to get a good base for the tip. I use a machined disc that sets on the inside of the lifter.

If the readings are taken at the same plane and the indicator tip is not 'slipping off' the area of the lifter you are reading from - something is wrong. I have never seen this amount of variation in their cams.
I would contact Isky and review your findings with them to get their advise and input on your measurements.
