seized 390?

Hello all,

Haven't been on for awhile. I had a lead on a junkyard with older cars that I visited this past weekend. I found a nice 390 4 bbl in a 67 T-Bird but couldn't get it to turn over. I only had a ratchet and nothing I could use as a cheater to get more torque on it. The owner tried today with a big bar but still could not get it to crank over. The carb has been exposed for I don't know how long although the motor looked in good shape. So do I give up on and assume its seized or is it worth taking the heads off and having a better look? He sells his motors for $250 removed from the car which is a good deal (obviously not if it is seized). A buddy of mine picked up two 440's from him recently for that price. He has a 1974 390 (presumably an FT) from a pickup truck already good to go.
