Default Cam timing question! What is my tolerance?

Ok so im degreeing my cam right now and i found it to be at 110.25* ICL. The cam is to be installed at 111* ICL per the cam card. Now i know there are times were you can have + or - 1*. Is this the case?
Any advice is appreciated
Thanks

You might loose a pound or two of torque at the bottom end and gain a HP or two at peak. There will be hardly any difference in my opinion. I assume that you don't have an adjustable timing set, so I'd button things up and move forward.

I do have the cloyes hex adjust timing set.. Just the adjustments on the cam gear it has little dots on the little hex adjuster and each mark is 2* and those are really small movements so im thinking im going to end up moving it to far since all i need is about a 3/4 - 1/2 a degree. So i figured i would ask around and get some opinions before i changed the timing. I also pmed pred z who specked the cam out.

The hexadjust is really pretty easy to adjust. It's your choice. Do a little trial and error or button things up and move ahead.

+ or - 1 or 2 degrees sometimes will not show much of a difference. Button it up and call it a day. Thats very close

Run it. You may check it on a different cam lobe, and it will be more or less.

True dat. Even that's to say that sticking a cam in isn't always just a guess. One combo may work better one way another may not.
