I have a YZ code motor in my 72. It has the 48 heads on it and Not sure if it is a 69 or 70. The previous owner bought it and had it rebuilt. It is in my car and runs great. Had a 69 Judge owner talking to me at a car show yesterday. He needs that motor. Not that I'm thinking of removing it, but you never know. I don't know the casting number or associated Vin. But I could try to look. Would I have to remove the water pump to see the VIN? Anyway, just from a value/insurance standpoint, any info on value and anything else is appreciated. You can also send a PM if you prefer.
