i want to purchase a gsr motor and i have the bar number under the b18c1 stamp, i wanna know if the motor is stolen..

 

You can check with the local police. Make sure to tell them that you are THINKING OF purchasing the block. Don't let them know who is selling it. They might ask you to take it in, in that case, don't even bother. If it does come up stolen and they have the motor in their possession, they will keep it. They might go for checking it by the VIN #s you give them
