verification usingCasting date

[Alexander S.]

I'm currently looking at a 75 without a VIN on the block. I was told the block was milled to get a little more power out of it. The casting date is K203. If records serve me, this is Nov 20 1973. I believe this to be a NOM but the owner insists that it is original; the eng was a surplus from the 1974 model year. The birthdate of his car is July 07, 1975. This doesn't add up to me. Am I wrong?

Alex, generally cast dates are only weeks(4to6) before the hit the production line those dates do seem to be way to late.

Agree with Ed.

I would also check the casting dates on the cylinder heads and any other engine components. This may help in determining what actually occurred with this engine.

I would expect 18 months for a complete original engine to sit around waiting for a car body is way to long. Maybe its a CE block or over the counter block.....or from another car.

Thanks for the input. I sorta knew that I was getting bad info especially after reading another thread regarding casting dates and assembly dates, but I wanted to get advice from someone with more experience at this
