I bought a SBC 350 engine for my Mud Truck. But I'm not sure about it, The number stamped on the Passengers side of the Block behind the Alternator is 16S406771 V0923CHC Does anyone know how to Figure out exactly what engine this is. I have looked online for sites Posting engine number but can find or figure out the ID. I was told from the person I bought the engine from that he thought it is a 4 bolt 350 from the 70's or 80's , it does have 202 heads, and a 500 something lift cam ? Elderbrock manifold and Elderbrock 600cfm carburetor.
