1973 dodge charger 318 good ideo or a bad one?

All depends on how fast you want to go. A stroked 318 can run real good but not nearly as good as a stroked 400 (stroked to 451 with a 440 crank) if it's done up right.

So lets say I build it into a 400 if thats possible right? then turned it into a stroker? Would that a) be possible and b) is that a good idea?
