Roller cam/lifter retro drop in, thoughts?

The price is possibly a problem,a great decision in the long run. Budget, stay flat tappet. Check out MRL Performance, here. He does Mopars only,and a head porter. Those go hand in hand,and cheaper in the long run.

I agree with the above. At least talk to Mike about what you're looking to do.....all your out is a phone call. He sell's a quality "in-house" lifter and he's also one of the best at recommending a cam grind for your specific needs.
