The 340 is the biggest POS V8 Chrysler ever made.

On the other hand, I do remember a very well done Vega GT with a 350 in it, and yes Monzas had v-8's but werent meant for any kind of horsepower that was eventually swapped into them, I believe they were 262 cu in or something like that, and then people swapped in higher HP 350's, used to pop the windows out from the body twisting. :)
