What's 1 1/4 inches of slop? Use the marks, when the slop gets to around 15 degrees going back and forth, the chains about ready to jump. If your chain jumped, you would have no compression.

An engine needs three things to run and you say you already have two, compression and fuel. I'd say your module died. Take it to any good parts house and they will test it free. Worth a try. Have you pulled a plug wire and tried to draw an arc?

ok,when you say that there should be no compression,,do you mean none at all or just very weak ?

Very weak, go ahead and buy a gauge, it's a good investment.

If you need to figure out how to realign everything, try the following link. It's for a 351 but all is the same.

No problem, sorry to hear of your dilemma.

The chain is not that hard to replace, it's getting to it that takes all the time.

I replaced the chain and sprockets on my '79, it was so loose I could remove the chain with the sprockets still on! Also, the bolt in the center of the cam wanted to seize coming out. Had to work it back and forth slowly inching it's way out. Don't want to break that sucker. Good luck!
