I'm just a hobbyist on building motor's as I usually just have the short block done at the local Machine shop. However this time I opt out to do everything on this build myself as it is my last. It's a SBC 327 with a small Journal crank. My problem is I ordered a Roller timing chain and though I have replaced timing chains, it wasn't the norm. It Had three slots and three different marks on the crank gear. On the outside of the crank gear It had a Square, Circle and a triangle. Thus the key way matched the outside symbols. Two of the marks are to set the cam 4 degree's up or back. I do not have that hot of a cam and was just looking to put it at the stock setting. I opt to line up the triangle with the dot. It should fire right up. No such luck.So I go back and look at all the pics. I took and it shows lined up this way that TDC is at the 4:00 position. Should not the TDC be in line with the top dot on the cam? Please one dot on each gear for the simpletons like me would be great. Any input would be fine.

With the engine at TDC, the gear on the crank should have the mark straight up at 12 o'clock and the cam gear should be lined up with the mark on the crank gear at 6 o'clock. If the cam is going to be installed "straight up", out of the 3 keyways on the crank gear, you should be keyed to the middle keyway. TDC timing mark will not line up in anyway with the timing set. You just set the motor to TDC and the setup the timing set. Hope that helps!

i'm wondering when u did the timing, where u pointed the rotor.. i'm with the crank at noon and the cam at 6 then put the dist in and point the rotor at #6 wire.. if your motor is all together then most likely your 180° out.
