Start from scratch...dont do anything else with the engine till you set the mech timing back on. Take the timing chain tensioner off, pop the valve cover and pop off both cams. Do not, I mean DO NOT turn the crank with the cams on and chain/mech timing not hooked up right. YOU WILL BEND VALVES. Think about it...piston goes up, valve stays open since you have the cams on. Only way to close the valves is by taking the cams out.

Once you have the cam off, turn the crank and put it to TDC. Have somebody hold on to the chain so it wont drop down into the oil pump cover. TDC = #1 cylinder all the way up and the mark on the crank pulley line up to the 2nd dot from the left. Hold your breath that the timing chain marks are on point. Would make it easier if they are, if not, you'd have to count the chain links.
