Bullet camshafts?

[brokenjeeper]

Curious if anyone had any experience with these. I'll be placing
one in my 401:

HC267/320 Adv. 267, @.050 214, .320 lift on 112 deg. lobe center.

It seems to compare favorably with the Engle 5054 with a slight increase in lift: .320 vs .313

On a side note, I noticed that while the oil relief holes are in place on the rear of the new cam, the raised boss is not. Should this be a concern? What is the purpose of the raised boss?

I think its there to keep the cam from moving back when the engine is running kinda like a cam button on the front. I dont know if its necessary or not.

As long as the oil relief holes are there, you're fine. The cam can't move back once the cam gear is against the block (as long as the front bolt is tight #-o ).

X2 on the above ^. The cam sprocket should hold it from moving back in the block. As long as the lobes are in good shape the cam should track back against the block, if they get flattened then it starts to walk.
