I was recently gave an engine. I was told that it was possibly a 390 or a 428. I called a dealership and gave them the numbers off of the distributor and manifold and they told me that it was a 352 manifold and Distributor. But the guy that gave it to me told me that the person he got it from put those on the engine. The Cylinder head casting numbers are D2TEAA on both heads. The casting numbers that I could find are 89-352on the front of the block and 51-352A on the back. I also found a number on theblock under neath where the starter mounts 2817-78 not sure if that means anything. The numbers I found under the oil filter are W1 - RH28. Would Like to know what I have so I can order parts to begin rebuilding it.
