Could my 340 block be filled?

As a quick check after the car is hot and will not fire I do use the timing light and see no light when cranking its safe to say I have no spark at all correct?
You're quite welcomed on the help. FABO is pretty darned good for that.

Well that is the point I am trying to make..... the timing light pickup has a sensitivity threshold and if the spark energy drops down a bit, it might not trigger the timing light but still have some spark energy. So that it why I would check it as suggested; you are truly going to see if you have some spark or no spark.... which is a very good clue.... and you also may observe that the spark is more yellow and less 'snappy' when hot..... another good clues. The timing light firing or not is masking some possible good information that actually LOOKING at the spark in open air can give you.
