Does it have headers on it? Maybe one of the new plug wires is too long, and laying against the header .. It has run long enough to burn through the boot and/or the wire and maybe it's arcing through the header at higher RPMs ?

Raise the hood at night and see if you see it arcing over to your header .. just something to try. I had a 406 in an old Firebird that as bad to burn through plug boots.
