Do you happen to know if there is a -# after the C8OE? Early '68 302 4V engines had a C8OE-F casting with a small 53cc high compression head very similar to the HiPo 289's. Most of the others should be between 58-63cc. I'm not for sure if the emission bump in the exhaust appeared in any of these or the C9's. I know the D0's did.
'72 TBA...
