Hi-Po block

Found a 65 Hi-Po block. C5AE-6015-E 4J23 date code, stamped 4J24F left front pad. Stamped 5F07K309663 left front pan rail. Registry is not showing this number. The block still has the Z-bar stud on the right rear so it was a 4 speed car. The block is at the machine shop getting the cylinder bores measured. Its probably been bored in the past. Bad news is someone has already made off with the main caps before I got to it. My intention is to take it to Columbus if anyone wants it. Doug at babebolt@yahoo.com
