You are probally right Kim. I could not lay my hand on a original 4 bolt right now but I am almost positive I still have some 2 bolt 440's in the pile. I guess I am just not a big fan of a 60 bore on a 396 for a original car and would sooner convert a standard 2 bolt to 4.I also saved and saved and saved BBC for that rare application which is why I now have a barn full of boat anchors too heavy to ship to the US where they are in demand. Did sell all of the square port stuff but 10 years too early.
Take care Joe
