if your current engine is in great condition, then no a 347 stroker kit is not worth the money. if oyu want a bit more power, then drop on a set of windsor jr heads, a performer rpm intake and 600cfm carb, and tri-y headers. also consider a set of 1.7 roller rocker arms. this is all bolt on stuff that can net you another 50-60hp easily, and will make a difference in how the engine feels, and would cost less overall than a stroker kit if you shop wisely.
