The 340 is the biggest POS V8 Chrysler ever made.

Did you know there was 327´s available with 375Hp from the factory?
Not trying to stirr **** here but the smallblock chevy is a good engine, the mopar smalblock mopar is a fine engine aswell and now alot of years later we can do a whole lot more with them than what was possible in the 60´s when these heaps of iron where designed.

I have a 340 and had one in the past that expired and realy if a need for another engine would show up i would probably go for a 360 instead unless i ran into a another 340block by accident. nothing special about them as soon as you start swaping out parts.

You have to be careful using Chevy HP numbers. They were more than a little exaggerated. Their longevity was short lived also. The only real POS engines back in the day were the Vega and Pinto, with deleted oiling to the valve train. The Chevy is not in the same league as the Mopar small block, but not a POS. It has nothing to do with HP numbers.
