Just saw this come up on a YouTuber channel. I read the forum rules and I don't think this breaks any rules, but admins, delete by all means if it does. Anyways, this guy finds a '67, seems to be complete, with a numbers matching engine, factory air, factory original center console, is also vin coded as an RS, and dude is going to LS swap it. He had decided to do so before he even had the title in hand. I have not disagreed more singularly with a car decision in my life...

He only has one video up but, if you want to see the progress, check it out

 

Well it's his car and far from being in great shape so .
Just a garden variety 327 2 barrel,I can see an LS swap being desirable but if I had it I'd keep the original motor around.
If it was an SS 350 or 396 it would be a different story IMO.
