Am I Going To Be Happy With This Camshaft?

Well I made a decision. I'm sending my cam and lifters to Oregon Cams. @Garrett Ellison swayed my decision after his shameless attempt to buy the old Isky cam. :poke: Just teasing Buddy. Thanks for the info.
The conversation with Oregon Cams was very productive and reassuring of my decision. Real down to earth folks. He even laughed at my jokes.
So I have two complete 340's and trying to make one good one but I still have a question. What is going on with these different looking lifters. The lifters with the extra little ridge in the body seem to have survived the best. I think it is an original Mopar piece. The same height lifter next to it is what was mostly on the Isky cam along with the other odd ball. The other 340 had 15 of the lifters like the one with the extra little ridge and one odd ball. So basically, I have a full set of 16 with the extra little ridge in the body to send to Oregon Cams which seem to be in the best condition.

They're good folks. I cannot sing their praises enough. I recommend them constantly and it falls on deaf ears a lot.
