NO..
Now excluding prototypes etc for a moment and concentrate on production only..
84-89 Corvettes had the ECM behind the 'bread loaf' on the passenger side of the dash. They also did not have a separate CCM, all the fuel calculations etc were handled by the LCD Cluster itself
90-96 (ALL: non-ZR-1 and ZR-1 90-95) had an ECM and a CCM.
the ECM is located above the battery. the CCM is buried behind the Radio in the dash.. the CCM controlled the LCD on the cluster. so any function of that LCD on 90-96 was handled by the ECM.
If you install a LT5 (best to go with production parts) I would suggest a 1990 or 1991. you would need to try to interface the engine harness with the 89 wiring going into the car at the driver-side bulkhead and passenger side pass-thru. You will also need to add the second fuel pump and wiring for the key if you choose to have full power as an option
