Reground Camshaft w/hole
#DR13-11 Solex II ?
This
is a fresh reground used cam. The front attaching flange
has been modifed with a bigger hole for a larger locating
dowel. This was probably done to use a gear that had been
redrilled with new bolt holes so the cam timing could be
advanced or just to strengthen dowel setup.Will not work
with your cam gear unless you modify your gear. This
appears to be a "Solex II" camshaft or was nicknamed the
"C" cam. It is stamped "25510" on the rear end. I haven't
had it since it was new so I cannot vouche for it's
authenticity. Duration intake and exhaust 292 degrees;
lift .458. No core required, sold outright.
