We do a lot of custom cams for the slant 6 engine. We could work with you to come up with something to work real good with what you are doing. If you get a chance call here and ask for Dave. Tell him you were on Moparts.com and I told you to call. By the way, we also have double roller timing chain sets and a chrome valve cover for that engine.
Good luck,
