LT1/4 timing chain slack
In the middle of a elec water pump install and pulled the timing cover to remove the water pump drive. The current LT4 chain has roughly 30k on it. If I rotate the crank to pull the slack out of the timing chain on the pull side I have right at 1/2" of slack. About every SBC has some slack in it but I couldnt find a spec that specifies how much is too much. Does this seem excessive?

I used the same chain...much cheaper than the alternatives.
