Can Timing chain get jammed?

The first time I install the 91 intake cam, the car wouldn't start. So I took off the valve cover again and found out that exhaust cam mark was off the colored link by one tooth. I think it slipped when I did it last time. However the intake cam was off by 3 teeth and I swear it didn't slip because the tie strap was in place. Last time the dealer did the chain for me when I blew the head so they could have messed it up. But my compression was at 200psi for all 4 cylinders. However my trap speed was only 87mph. How much horsepower would a tooth cause.

Now the big problem is after I realigned the chain with the sprocket and tightened everything back on. I couldn't turn the engine anymore. I'm wondering if the chain might have gotten jammed somewhere at the bottom. Does the crank sprocket have enough slack for the chain to slip? I don't dare crank the engine for fear that it might break the chain and break all the valves. Please give me some advice on this one guys.
