I have run a Mopar Performance .590 solid lift purple cam for years. Want to switch to a solid roller, but stick to something "comparable"., or basically the same cam, except for it being a roller. Do I leave the duration the same and change the lift or do both need changing to keep it the "same"?
Bowtie guys tell me that a solid roller needs about .100" more lift than a sft cam to maintain, but with mopar lifters being so much larger, do they "act" like a roller already?

Thanks, Brian
