--Highly doubt that its the chain. If it was the chain the engine would barely run or have any power. Put the timing light in your tool box. Old engines have a bad habit of slipping the outer collar of the harmonic balancer. So if you're the type of person who only sets timing with a light it's going to be difficult. I would encourage you to abandon the light for right now. At idle bring the timing up till the engine speed flattened out. Then dial it back till the engine bogs. Just the slightest little bit. Lock it down. Take it for a drive. This is the old school method of power timing. Every engine I have ever worked with has had a slightly different tolerance for ideal timing. I rebuilt my 440 3x for various reasons. Each time with a different cam. And each time desiring a different advance on the distributor. If the timing is too quick on initial. It will crank hard when hot. Just pull a little more timing out till it cranks satisfactory. This is the way I set all my mopars and all I work on For others. Once you find the sweet spot. Check it with the light. You may have to make a new mark on the harmonic balancer it will be soo far off. Now if you install a new harmonica then a timing light is a great tool.My opinions have been shared here and may not be shared by all who read this. That is ok. This is the way I do it here in Indiana.Jason

Subject: 318 poly woesWhat would your guys guess be if you had to advance the distributor quite a ways to get it to start?--Also if I set the timing at 10btdc in about twenty seconds it is at about 7 or 8 btdc.Sounds like it could be a chain issue. But I want the pros opinionsNeal
