My 87 is carbed... but my RA in college had an 87 with SPFI... I think in 87 it was something along the lines of

 

A: CA models were EFI and 49 state were carbed

or

B: Carbed first half of the year, then the 87.5 was SPFI...

 

My guess is A though.

My 87 4 door 2WD was SPFI, not a california model either. I had a friend that had an 87 GL wagon, DR 4WD with a carb. Both PA cars (although I think mine originated in NY).

probably belonged to someone who worked at a dealership, easy access to all that stuff.
