The 340 is the biggest POS V8 Chrysler ever made.

I just have to say most of this (racing/performance) stuff is pretty esoteric.
Over years I've had more than one mechanic express an appreciation for the reliability of a LA.
One wanted to buy my car and neither were brand loyal.
I want to get from Point A to Point B.
Not just go a quarter mile.
So, is there a fundamental difference in engine design between LA engines that would make any a "POS"?
I can't speak to the off the shelf comparable GM engine since I've never had one.
