I cannot tell you the specific differences, but the L88 was the all out racing engine. The L89 was the tri-power L71 engine with alumn heads.
The big blocks were:
L36 427/390hp
L68 427/400hp (tri-power)
L71 427/435hp (tri-power)
L71 with the L89 Option
L88 427/430hp (rating downgraded to keep people from buying it for street use)
