I want to build one of these 4.25 stroke B motors for the street but have been worried about wear. When you say they work really well do you mean run well, wear well, or both? I've been wondering if I need to keep it at a 4.15 stroke for the slightly longer piston and rod ratio. This will be the only time I will be able to build an engine.
