If anyone has any suggestions for a 65 elky please let me know.
I fail to see what the suffix code will tell you that is of any real value. Things like what foundry cast it, and the assembly month and day, and what vehicle the engine was installed in originally means basically nothing in the greater scheme of things.
What you want to know AFA for buying parts, etc. is the displacement and when the block was cast- and even the date isn't important if you can tell if the crank is a large or small journal, if it has a 1 or 2 piece rear main seal, and whether it is equipped to use a factory hydraulic cam.
