I ran into this recently on a 440, I bought a -.005 chain and that made it nice and tight mine had more than .160, I didn't measure it but it was probally closer to .250 total deflection In a stock block according to the owner I'm not sure if Cloyes still offers -.005,-.010 and -.-15 chains any more
