Change in plans... Anybody used a "retro-fit" roller cam in a Magnum?
Stock original magnum roller lifters that are in good shape with no roughness or binding of the roller wheel and no rust or pitting/flaking of the roller wheel have worked well for me. A regrind cam is a good option to have but also requires new longer pushrods, evening up the cost a bit after all shipping and cam snout extension is factored in. I am not against them because you can get a nice custom grind that way too. Also, just for information, I installed one of those cam extensions on a 360 magnum about 10 or 12 years ago along with a Mopar short snout cam and it's still going strong to this day. I filed it a little to make sure it went together smooth and used red Loctite on the cam bolt threads and it has never come loose with a mechanical fuel pump the whole time. It's in my brother's car and gets driven plenty on summer weekends.
