A friend way-back-when had a 64 Chevelle that had a 275 horse 327, but it may not have been original. On the cam question, my dad's Motors manual from that era listed a whole bunch of different cams, but that manual is long gone. It would be interesting to get into an older manual and acrually look this stuff up, but I don't have one detailed enough that it lists things like cam profiles, or head specs. Does anyone else?
