Y motors are basic 307 motors.
9 motors are also 307s but have a few upgrades.
The 9 motor uses an Olds 350 harmonic balancer and the Y uses a different smaller, crappier balancer.
9 motors have upgraded better flowing water pumps.

VIN Y is 140 HP, VIN 9 is 180 HP. There should not be any real 87 442s with a VIN Y motor.
