7afe and 4axx have the same diameter bore, stroke difference is in the crank throw. 4axx rods wont work, the crank journal on the 7afe crank is a larger diameter iirc. however 4axx pistons will work, the piston bosses have to be machined to fit the 7afe rods.

speaking of rods, its about $700 a set for 7afe rods from...i think its eagle.
