I have a running 2.4 LD9 engine for sale, its still in the car. I am going to be swapping in a built 2.3/2.4 hybrid engine in this engines place. Bottom end has about 70k and is stock from my 01 z. The top end has a PnP head with some kind of beefier than stock springs and SS valves. It has 87-88 2.3 cams, .340 In .350 Ex lift and 212@50 duration, and the old smooth, steel lined lifter bore, cam towers. 87-88 tubular intake and stock throttle body included. I was going for midrange torque but I never got a good tune on the car to see what it could do.
$750 obo for whole engine
$400 obo for bottom end
