The stamped pad at the right front cylinder head will have numbers that correspond to a vehicle model it was original to. The casting number for the block is on the LR of the engine above the bellhousing area. Head castings are under the valve covers. Then use the Mortec site to get more info.

After that trade it for a six cylinder.
