This is the complete bottom end with pistons/rods/crank/everything. the #1 piston ring needs to be replaced. Good for those of you who want to build up a bottom end. The scarring is very minimal, Honda tech manual says you can bore up to .050" over stock, and this is well within these specs, so you wouldn't need to sleeve it (obviously unless you were putting in aftermarket forged pistons/rods etc.). Asking for $300+shipping (pick-up preferred). I also have the complete head for this motor.
