| The rods are not 428 rods. |

They are 390/391/410/428 rods. They sometimes get drilled for 13/32" 428CJ/PI applications, but most often just get drilled for the 3/8" rodbolt.
Note that 390+ CID FE/FT rods with 3/8" bolts since mid-1963 are all made of forged SAE 1041 steel, and all of them have the same strength and balance specification. Part numbers vary, but the rod's the same.
Since you can get high-technology ARP bolts for the 3/8" rods, these can sometimes be considered superior rods to 428CJ/PI rods if the CJs have well-worn bolts. Also, the ARP bolts for 13/32-drilled rods are apparently not as good a design as the 3/8" bolts (though they may be superior to stock CJ bolts), so if you're gonna sink any money into buiyng a set of rods, it might as well be the 3/8" jobbies, since they usually sell much cheaper than rods drilled for CJ/PI applications.
By the way, you have a 390, though the 352 sighting inside the water jacket is interesting. I've heard of just a couple "390" marked and a few more "428" marked sightings, but yours is the first "352". Thanks for the info. This is good to learn.
