What Can Be Dome With a Chrysler 400?

A stroked 400 is a strong combo, but a stock stroke can run fine as well. The problem with the 400 is compression. A set of KB240 pistons with closed chambered heads will take care of that, or if you are building a no-budget car, then run a set of smog type (.040") over 440 pistons. They will raise the CH roughly .100" over stock in a 400.
