Getting back to the roller cam lifter comments.....I'm in the process of putting together a 428FE with the Comp roller cam, with solid lifters.
I have become concerned about oiling the roller wheel in the lifter base....just based upon what I'm reading....I'm thinking that an 
oil like Mobil 1 might be the best choice to ensure adequate oiling to the wheel....too bad there isn't some kind of drilled lifter that would take adavntage of the pressure system already in place if your were using a hydraulic lifter......
Anyway I'm wondering about anyone else's experience with roller cam lifters and 
synthetic oils?
