OK - here's a new Slant 6 article in Hot Rod (checked the date this time - Aug 2017 ;-))

Take your pick, there are 19 listed. But if they really did use a 6.658 rod, then that is a custom job...

That's about a stupid rod length, since there is only .041" difference between that and the stock 225 rod.

That said, I always like to sit back and watch the same people on here ***** about how no one ever does Chrysler builds, then when someone does, they ***** about it.

That last part isn't directed at you, kesteb.
