Still have problems.
Working on red blocks for 40 years and never had issues like these.

When cold it starts right up and idles smooth.
Once it reaches operating temp it will miss at idle and even stall.
Over 1,000 rpm it seems fine but I could be not sensing the miss, not sure.
Over 2500 rpm, there is a major miss/bog that will last for seconds and then smooth out until I decelerate at which point it will repeat the miss/bogs.

Here is what I have recently done;
New fuel pumps & filter
Swapped in numerous ign amps
Swapped AMM
Swapped in coil
New plugs
New SP wires & hi-tension lead (not Bougies)
cleaned injectors (nice patterns)
Swapped various relays (FP, RSR, etc)

I keep coming back to ignition, but fuel keeps nagging the back of my mind.

The dizzy cap/rotor is 5 months old but not bosch (couldn't find one locally when I needed it, same with wires).

Major engine components (head, cam, pistons, etc) are new or machine shop freshened.

Car was running great for 4 months after rebuild.

The only major component I have not addressed is the turbo (did check internals but did not see any issues, bearings ok, etc) but do not see where that would affect idle operations. Unless the vac actuator could... will check that again.

I know this is probably something simple but I'm blind to it.
What am I missing?
