slack in new timing chain set

[Hazegray]

I'm rebuilding a used motor 5.0L outta a 92 Mustang and in the mist of installing the new timing chain set, I noticed about 1/4" slack in the new set. I've done some research and consensus is that the block was aligned bored at one point, thus causing the slack. Does this make sense? If so, can I order a small chain or larger camshaft gear to take up the slack?

1/4" which way, top and bottom of gears or inward from the sides?

Sorry...inward from the sides. Like a worn timing chain...

look here, you need to determine how short it needs to be

Great! Thanks a lot for the info. My bro sent me this info just a second ago (better late than never I guess) :
1/4" of slop= .002 to .004" line hone set
5/16" of slop = .004 to 006" line hone set
3/8" of slop = .006 to .008" line hone set
1/2" of slop = .008 to .010" line hone set

so you need cs3071-4


maybe cs3074-2

I've had a few engines aligned bored. How could an align bore, properly done, have any affect on chain length? wouldn't this mean the crank was off center?
