i hav a 69 olds cutlass suprememe. When we bought it i assumed the engine was the same. Unortunately I dont think thats the case. The number castkeded on the engine is 557752-3b. I checked a few internet searches and it comes up as a 77-80 350. I figured you guys here would know if thats true or not. Please let me know.

Thanks

Yes, your engine has been replaced at some point.
