1/2" UNC but not the length.  I'm trying to figure out what ARP bolts you
would buy to replace the stock bolts, and also one that's 1/2" longer to allow
for "strapping" the center main.  If I had the dimensions (length) I could try
to cross reference the engines that ARP lists main cap bolts for.

Tony, 3.5 inches under the head.  I can give you the ARP number tomorrow, but
don't have access to my build log right now.
