camshaft end play?
camshaft end play? ok i just installed my new cam into the block and secured my new cam retainer plate to the block (new countersunk plate and bolts= 12ft/lbs of torque). now my question is how much is the cam supposed to move backward into the block when i push it in and pull it out? seems like it moves alot, is that normal? also when i secure the cam gear (timing set gear) to the cam, step back and look at it, it seems like the cam gear sits farther back into the block than the crank gear does. not much maybe just a tinny tinny bit. is that normal? when i turn the motor over by hand all looks good, turns nice and easy and doesn't slack the chain.... just seems like to me the cam gear and crank gear would be in perfect alignment but maybe the cam moves a bit for clearance????
ok so i just read on comp cams website... its says that it is not necessary to check cam end play on any cam that is used with a cam retainer plate... is this correct

Seems to me that you would want to check endplay anyways. If you didn't have any clearance, the cam would grind into the retainer plate and not only put a lot of debris in the oil, but cause a lot of power loss to friction. I'm sure the Torrington bearing in aftermarket timing sets wouldn't last long like that either.
I always check, and on LS1's I usually see .005-.010", which is fine.

All the cams I have done have been loose. Makes you think they are too loose but it seems to be the nature of the design. At .007 you should be good.
