I have a 1969 RR with a non-matching 383. I finally removed it from the car to get rebuilt. I tried looking up the block casting number of 2488130-1 on the internet but for some reason it isn't listed on any sites? Does anyone know why? Thanks!!
Stare at it again.. I suspect it's 2468130, not 88
No cast date on it? Casting number covers a lot of years.
