Is the 1228079 ECU a direct swap into an 85 z28?

I bought this ECU which comes with the ACFZ PROM.

https://www.ebay.com/itm/1987-1988-M...53.m2749.l2649

My research seems to show the ACFZ came out of the 87-88 Monte Carlo SS with an auto L69.

Does anyone know if this is a direct swap into my 85 z28 with a LG4 and a 700r4? I don't have AC which I think helps.

My goal was to get to the newer ECU and a PROM with a bit better spark map. I'll plug it in when I get it but I'm curious if anyone knows how (un)successful I'll be
