Hey looking for info on 8.1 salvage yard said they came with an allison behind them. I want to put one in my firebird but want to install a 4l80e behind it. Anbody with info on this swap please let me know. Is bellhousing the same as 6.0? Can I get a flexplate that will work? Can I use GM pcm and reprogram it?
Suburbans and Avalanches I believe had 8.1/80Es. Just scout out a VIN to get the correct parts would be the best bet.
It'll bolt right up, there are no SB/BB bells like in the Ford world.
