Camshaft in a 65 273

Another vote (and current user of it) for the isky e-4 solid cam. It pulls 15 inches of vac at 750-800 rpm comes to life around 2700-2800 pulls strong till 5200-5700 depending upon where the cam is indexed at. Mine is stright up & pulls too 5500 all day. You cannot go wrong with this cam in a 273. Works even better with the higher
Compression motors like my own & TMM's engine. (I forgot to add I also installed crane iron 1.6:1 rockers to give a bit more lift.)
