Default 82 Corvette Timing problems

I purchased a 82 Corvette that had been stood for a while so changed the plugs, cap, rotor, oil filter, throttle position sensor everything that goes along with a full service.

The car starts and runs but the timing is out. Currently the car is firing on 6 degrees before TDC on cylinder 8 instead of 1. I disconnected the ECM lead to the distributor and found TDC on number 1 cylinder set the cap and lead to fire on cylinder 1 and tried to start the car.

The car wont start or even try and fire if I set the timing up on cylinder 1, if I set the car to fire on cylinder 8 first the car starts and runs.

Any ideas I am completely stumped as what to do next? I have set the timing up on many cars and never had this problem.

When you set #1, did you have #1 TDC on the compression stroke or the exhaust stroke?

Just to update this thread I found the problem, the harmonic balancer had slipped and was causing all the timing problems. Replaced it and timing is now good.
