If your 100 the crank pin your using is correct and the static timing is bang on we need to explore another reason for the low intake vacuum .
Compressions
Air leak check
Throttle plate
Valve clearances
All the basics but until that vacuum.reading is up we will never get the engine to idle , the puffing noise interests me could you perhaps video the symptom it may help more accurately understand the concern

And the late ignition event.
There's sommat amiss here with this cars info & symptoms

I can't remember but is the crankshaft timing gear sprocket a fully floating type or is it keyed !

by **Dcunning35** » Mon Jun 12, 2017 9:36 pm

Both of the cams and crank are floating pulleys.

I would double check your crank pin and make sure your piston is at tdc physically when up against the pin .

Exhaust valve timing looks advanced - . Ignition retarted

As Eric O. would say : THERE IS YOUR PROBLEM, LADY

Car pures like brand new....0 Error codes present, Full Power
and not 1 Misfire.Vacuum readings steady and at normal specs.

Will do some after Waveforms in the next Week or so, but just
follow up, and not leave this open-ended....

That must have sounded terrible when running, and starting that engine must have been a nightmare!

Had the timing jumped too ?

Otherwise that broken plate does not explain the low vacuum or have I missed something ?

I believed the timing had jump from his scope traces!

I not sure whether the engine actually run!

With this in mind, I'm thinking along the lines of the following;

When the starter motor pinion engages the ring gear the plate turns much faster than the crankshaft because 'yes' it's detached, hence low speed turning crankshaft = slow piston movement, hence low vacuum, or would you think I have missed something myself?
