318 idle rough after new cam break in and 2 short test drives???

Could be one or two teeth off on the cam timing.
Well, like I said on start up 1000rpm, it was fine took a 5 mile trip, done real good, at the stop sign before going back home, idle was not much lower. then got home, went to back in the drive way, dead drop to 500rpm about to die in gear and next day will not idle on Start up!
