My 76 280 has this motor in it... L28 187452. What year would this motor be from? Its not the original motor. Im guessin like 77 or 78. Is there a site that I could use to find this info?

My l24 has close to the same # and it is a late 73 if that helps.

188589

John, the number of an L24 would be of no help. My 78 has the original engine L28 275875 and the car has a 5/78 build date. Doubt that yours is a 78. Likely a 76 or early 77.

I tried to help.I was told my engine was a late 73.You think it is more like a 78? It is not the original motor so the later the better.

Is it an L24 or an L28?

mine is a l24

L24s were only used through 1973 in US cars.

So is there a site out there that might have dates for the motors numbers?

Not that I am aware of other than this one that shows some ZXs.

Engine L28-081399 is from a 76 that belongs to another member here to give a general idea of the range.

Stephen,

I was reading this and thread and thought to myself that number looks fimilar. Then it clicked thats my engine #.

There is no site that tracks our engines and cars like they do today.
