It's no wonder the Slant 6 is so great!

I've had them that way, I've also had a few that surprised me with how they ran.
Id much rather trade 12 sec 1/4 miles with all of today's computerized bullshit and "locked", Big Brother dictated/mandated for the simplicity of a /6 or a carbureted 318 for a daily driver... You'll be sorry when there are none left.
The /6 definitely has a whole lot more value than "ditch fill" or "boat anchor" as some claim
To me you want a boat anchor go find a 454 especially one of the last of them.
