Or worse, hearing (reading) the justification to put an LS in a Mopar, or anything non-GM really.
Agreed. Every time I read a thread about it, I gag a little. I also don't like small block Chevies in old fords or Mopars. I totally understand they do it because it is usually way cheaper, but I can't stand to look under the hood of a 32 or 49 Ford and see a SBC.
