SBM Roller Lifter Choice

Boy you are right they are proud$ of them.
I will be honest with ya I not a big fan of Comp. I paid good money for the Comp lifters I have now and they are junk. On top of that they have some of the worst Tech and Warranty service that I have witnessed.
Because of the design of the Mopar oiling system, imho you really cannot use a hydraulic roller cam properly in these engines, and there really is no benefits. I would just run a regular flat tapper on the street.
I would not say that your issues are with comp cams, but an improperly prepared block. Anyone who claims they have a drop in hydraulic roller for a sbm is not being totally honest imho.
The sportsman lifter really are aimed at the racing crowd, but feature for feature and even at that price, I do not see anything that beats it imho. Who else makes staked axles to get rid of the clips.
