Katech C5R chain too loose?

I know there will be SOME play with the timing chain, but should I be worried about my chain being this loose?

Don, thank you. that is very helpful.

Robertway's write up shows cam bolts require 26ft/lb, but your book shows 55ft/lb plus 50 degrees.
I've already put locktite on the bolts and torqued them to 26ft/lb

Should i go break torque and torque at 55ft/lb?!

You used ARP bolts so follow their torque spec of 25 ft-lbs so 26 is fine. The balancer was easy, I used the ARP bolt without the washer to get it started because with the washer it was too short. Once I got it so far I put the washer back on and drove it home, no big deal. With ARP balancer bolt you just torque to 250 ft-lbs.

Thank god for ARP and getting away from wacky GM torque specs on those stupid TTY bolts.

They need that looseness cold to allow for expansion of stuff when hot. You'd be amazed how much tighter a timing chain gets on a hot motor. If you start out any where near tight cold, it will quickly get way too tight once the motor warms up.

Another good reason to never woop on a cold engine, let it get warm.
