If the cam/crank/IP are all still in time, buy me some lottery tics too!

Seriously though, the chain and timing issue might not be too big of a deal. If the cam sprocket didn't entirely come off or go haywire, supposedly the chain should still have tension on it.

So... that could mean that the IP and crank are still timed properly, but the cam is out of time. When you have the cam/sprocket out, you'd just artificially provide tension where the cam sprocket would be, then turn the crank to where it needs to be.
