You have alot of home work to do.  Start in the aarchives, and search for 
related items.

The 727 was an underhood version of a 730.  The 730 was used in one TBI
application (one injector).
There are hundreds of ways gm organized the tables for 256/512/32 proms.
Some different auto to manual tranny.
The 730 was used on 4-6-8 MAF/MAP TBI/TPI Distributor/DIS applications

PT is still really tough, and was in ER several times lately, but hanging in 
there.
Took 2 hours but did a 2 mile walk yesterday, payin for it today.
At the limits of meds, one milligram dosage error was what some ER stuff was 
about.
