I drove my P/S 68 Barracuda with no pump for quite a while, trying to find a good one. Iron head small block with 255/50-17s. Not the easiest thing to drive, but unless you are spending most of you time in crowded parking lots quite livable. I've got a 20:1 manual box now and I'm curious to see how it drives and what the actual weight is with the Eddie headed B engine.
