360 will not start, any suggestions?

Some more. If you even suspect timing chain problems, and you know what cam you have you can estimate cam position by figuring out the timing event. Look at the specs for the cam, example:

FIRST make SURE the timing mark on the balancer is correct by using a piston stop. If you need destructions, post back You MUST find out if the TDC mark is correct before you do anything else

To check cam timing...............

Refer to the chart below, right out of the 67 shop manual, this shows a 273 2bbl, but refer to whatever cam you have for the proper timing

Notice that the intake opens at 14BTC. Hell you can estimate that with the factory marks. You can LOOK at the 5 and 10 marks on the timing tab and eyeball how far another 5 BTC would be, and if you can't, just transfer the measurement down to the balancer so you can SEE what 15* looks like. Just rotate the engine with a wrench while watching the no1 intake valve. As soon as it starts to move (this is a "rough" measurement) is close enough.

Also, remove the cap, watch the rotor, and move the balancer back and forth with a wrench, watching for rotor movement. If you have more than 10* crank movement with no rotor movement, suspect problems. Yet another check is to pull the fuel pump (small block) Use a light and mirror to have a look. Is it a nylon top sprocket? See any wear, damage? Rotate the enine CCW so the chain slack is on that side. You can stick your finger in there, if they're not to fat, and feel how much slack is in the chain.

So how far WILL this change if a cam drive slips just one tooth? The cam sprocket has 46 teeth, the crank has 23 If you figure how many degrees per tooth, this means that just one tooth on either sprocket off means the crank is off by 15. 65*. Now a car WILL run (poorly) just one tooth off, I don't know about two. But the point is, you are trying to estimate cam timing, and you think it's within 5* then it's probably OK, because it would have to be about 15 1/2* off to be just one tooth off
