I know the TCI boxes swap among the 80s but were changed in later years (why, different timing curve?).

Are the pickup coils all the same?

How about ignition coils, caps, and wires?

How about wiring harness?

Boost controller computer?

Etc.
 
The ignitor changed to digital electronic in 1990. As far as I know the base timing curve is the same but the supplemental advance maybe different.

You can swap wires, boots, ignition coils. Starting circuit cutoff system is a bit different. P/u coils and flywheel aren't interchangeable...only 1985 through '89 and then '90 and up.

Vboost controller is interchangeable. Harness is different. If you want to go to late model ignition it's easiest to find a late model harness.
