I grounded coil positive to block?

I finally just got my 408 stroker running and was finishing up the timing when I grounded the positive terminal of the coil accidentally when I was trying to tighten the bolt on the distributor. Now it will not even turn over? I looked at the fuses and they seem to be OK.It does have the MSD box and distributor could I have done something to the box?
Thank you Christopher
