My buddy came across a 5 bolt SBF engine that appears to be recently rebuilt. Assembly date is 3K9C. We were wondering if there was a way to tell if this is a 260 or 289 without pulling a head or valve cover. Is there an external way to tell. I first thought of the timing pointer but that would be the same for 260 or 289 I think. Any input would be appreciated. I know 289 heads had the raised casting numbers on the head but not sure about 260 as I have never had one apart. We may end pulling a valve cover.
