I was out at Mo-Kan Dragway at the Hot Rod reunion yesterday running in the Super Modified class. Later on in the day had a couple guys come over and talked about the car, what the paint was, engine, etc. One guy had a '69 Dart himself, but they were both sort of perplexed at the fact the engine was a 340/417 stroker. I explained it about 3 times on why it was that way. Bigger crank, different rods and pistons, pistons move further in the cylinder which creates more cubic inches of volume. Simple right? The Dart guy's buddy then asks "So since it's bigger now, you can put big block heads on it right?"
