Can't find VIN# on engine

The machined pad above the pan rail you speak of and I read about in the manual is on right side (passengers) correct?? I scrapped paint off the length of the block at the pan rail. I didn't find a machined area or stamped numbers . . . .

you are checking the passenger side of the engine correct ?

If it has an F383 stamped on the ID pad then it was installed in a 1970 model year production line vehicle.

why are you looking for the vin ?
