340 camshaft

They are great grinds for old technology,they work good.There are alot of grinds that would work great for your set up but Im assuming you want the idle of a tight lobe seperation with fairly moderate duration and lift.I would suggest this grind from lunati over the isky though,its a bit more aggressive but has close to the same numbers at .050 duration and the same 108 lobe seperation so idle will be similar. http://www.lunatipower.com/Product.aspx?id=1529&gid=277
