Bill -- when I bought my 70 Z28 new at Doc Stewart Chev in Clovis NM ... it ran pretty strong. In fact, I took it to Ernie Walker's Amarillo Dragway (3683' altitude) and raced in in B/PS under NHRA rules. At one time I held both ends of the record at that track -- 13.88 @ 104.22 ... factory Goodyears and thru the exhaust. I didn't think that was too bad considering the altitude, etc. Craig
