LM7 swap with Firebird gauges??
Hello all, I did a search and didn't find anything on my question. I have a 1975 Firebird that will be receiving a turnkey pullout 5.3L swap. My goal is to install the functioning dash, center console, and partial door panel interior pieces from a 4th gen 'Bird. My ultimate goal is to have a fully functional gauge cluster/steering column, minus silly things like a check engine light
So here is the rub, can the truck ECM/harness's run the 4th gen Firebird dash panel, and can the dash A/C controls operate the 5.3's compressor for function icy cold air? Any help would be greatly appreciated.
Thoughts to consider:
I plan on running some LS1 parts such as the intake and new cam, so im guessing a re-flash will be in order, would this reflash of the 5.3 ECM be a solution?
Should I just pitch the 5.3 ECM and get an LS1 ECM, and would it work?
