Sbc engine identification
I recently purchased a 1981 Z28, I bought it based on how great it runs, it's in decent shape and the price was right.
Now I want to find out more details about the engine. The numbers on the back of the block are 3970010 and on the front, behind the alternator are K12 08 CNR.
Through research I've found the first number is very common and according to the three letter suffix (CNR) on the date code says its a 1970 350ci 300hp. Is this correct? Any help would be greatly appreciated. Thank you 😎🏁
