I’m just trying to narrow down what this engine originally came out of. It’s in my great grandpa’s ‘69 Chevy PU. I think I’ve put most of the info together so this is double checking myself really. The stamp behind the alternator is 13C134498 and then T1023CKL Ok so If I put all the puzzle pieces together right: 1=Chevrolet 3=1973 C=South Gate, CA (Assembly) And the rest in that is the original partial VIN T=Tonawanda,NY (Made here) 1023= Oct. 23rd CKL= 1973 tur hydro, Calif F A B Double check me! Am I correct? If so, is there a way to narrow down what exactly it was originally in? And, further proof that I’m totally new with this... what does “tur hydro” mean. I’m a book nerd mom that has never worked on a car or truck in my life, but I have always wanted to and was able to buy my Great Grandpa’s 69 this last year. I am the 3rd owner and it’s all been in the family. Everything I am reading assumes some level of experience. Engine wise, I wanna make sure I do right by this old girl! Any advice is appreciated.
