hello to all my name is Casey
how can I find out what gm motors I have, using the numbers cast on motors block and stamped on wings ?? P,S, I,m probably in the wrong forum, but I don,t know what else to do. Im am NOT good with these cumputers.

 

Welcome from Florida. You can search on Google using the numbers stamped on the block. If your vehicle has the factory motor in it, you can search using the vin number.
