W2 Stroker sale.
To answer your question with what you have there I would take it for about $4500 to $5000 with out the carb. This being based on a cast crank the lower end (but better then stock) rods. Econo heads. Any motor that I buy I would tear down and freshen up if I didn't know the motor and see what it did. And no offense but I don't know you personally so I take what the owner says about the motor with a grain of salt and check everything. I have seen people buy a motor that was "race ready and strong" and then came apart in three runs.
