Before you start worrying about the "grenade" part of the engine, consider the fact that you still have a 4 inch bore with 3.5 inches of stroke. Good rod to stroke ratio and piston speed that is desireable for an everyday driver. If this is the engine in your Galaxie, go for what you can afford. Cam is a bit weak and little things to improve is where I would recommend going. Not everybody wants to or can afford to drop big bucks into a monster cube motor. If you want to keep the 352, start with the basics and improve the flow and performance without overkill. Those motors have a bad reputation but it can wake up and be a good cruiser.
