Neither the comp 268 or the 260. This cam design is antique, slow rate of lift.
If you want to go comp cams have then custom grind a XE256H which is their Xtreme energy series, this cam will give you good low end & mid range power. This is a modern design & will require the valve springs they recommend.
Also get some 1.6 rocker arms, if you can afford it get the 1.6 roller tip rockers. Mike offers these at classic inlines.
If you don't want the clay smith cams, call Jerry @ schneider cams.

All the rest are custom order if you have the time.
