Hey Dave, the deal here is the p/s and brakets are where the bucks are. A 402 that needs work is really not worth all that much. It's not like a #'s matching thing as it will more than likely be going into a small block truck. But figure a runner 402 that needs pistons and bored along with new bearings and the rest would be worth something around $500.00. Now add all the brakets and p/s setup you can add $150-$300. So, I would feel in the neighborhood of $800 would be tops and anything less would be a pretty good deal. This is just my personal opinion and good luck.
