New timing chain, allowable slack?
New edelbrock timing chain, went on a lot easier than others I've done (which normally seem to be banjo string tight), just wondering if it may be a little too loose. I can just push a straightedge to the links with a 5/16 bolt in between it and the chain, and I get .030-.040" lash at the cam gear. I did this by hand, and measured with calipers, so I'll admit it's not exactly precise. This engine has been align honed, and I'm not sure if the shop didn't cheat and take a bit from the block. I also tried a new ProGear chain I have on hand and it was only marginally tighter. My FSM only gives maximum wear tolerances. Opinions, please?
