As others have said, the proper cylinder head work and camshaft is a CRITICAL choice. The problem with Mopar cams is the fact that you can NOT in any way shape or form, get the numbers you NEED on available cam cores. So that means a custom billet core cam. That's a $1500 camshaft and most balk at that and then wonder why the stuff won't run or is timing sensitive with big loads of nitrous.

But you might be in luck........LOL!!! I just ground Jake Gier a new billet core 55mm cam for heavy nitrous use. Fed Ex lost the cam, so I had to get another one started.......THEN they found the cam and now obviously won't pay the insurance claim. The new cam is likely far enough along that I will be stuck with it. So I will likely have a billet core 55mm nitrous cam in stock and on the shelf. But as I said, they are not cheap
