I just pulled the BBC/TH400 out of my 71 2wd blazer. I have purchased a 5.3 4l60 for my swap. The center line of my existing bbc mounts and tail shaft measure out to be within a 1/4" of the center line of the ls mount and tail shaft. It looks as if everything would line up pretty well. I was wondering if it is possible to use adapter plates with my BBC mounts for the install or if I should should change them out to SBC? Any advice or insight is greatly appreciated!

Thanks,
Mike
