So I recently changed out engines and have my old one laying around. What exactly is it worth if I were to sell it? I have a potential buyer but I don't know what to ask for it. The bottom end has roughly 10K on it, the top end about 1K. On the chassis dyno it made 224hp, 256ft lbs, with a 30lb flywheel, 11" clutch, T-5 and 3.73 gears. A 300hp mustang with intake and exhaust got on the dyno after me and made same hp and less torque. thanks guys.
