I suggest a restart according to the procedure (probably missing a few obvious detail steps) I mentioned before. If you are as much as 30 degrees off this could be enough to bring a valve in contact with the piston. I doubt it's that much but better safe than sorry. You could do as BC said and tense up the chain and try and turn it. See how far you are off before going more drastic with pulling cam and lifters.
When you retime, you absolutely must mark the chain and cam gear before removing it to reinstall lifters. Use nail polish..works great. Or testors paint.
The big problem is the IP.
AFAIK, you cannot retime it by eyeballing it. You'll need the RIV tool to get it right and may involve spinning the IP shaft (if you don't have any rotation left in the pump).
Do you have an FSM? If you don't let me know and I can send cam removal pages...
