Blazer / GMC Jimmy of the same year.  The Olds is full-time AWD, with
standard ABS.  The exception I noticed is the CR is 9.2:1 on the Olds
(@200hp!), and 9.3:1 (@160hp) on the Blazer.

Doug, the 92 VIN W (L35) engine, which uses Central Port Injection, is
rated at 200HP; the CR is 9.05:1, not 9.2:1.  The 92 VIN Z (LB4) engine,
which uses Throttle Body Injection, is rated at 160 HP; the CR is indeed
9.3:1.  The 92 Bravadas and S10 Blazers came with either engine.  According
to Ludis Langens' site (www.cruzers.com/~ludis/), the Z engine uses a
16144288 ECM, the W engine uses a 16156647 ECM.
