Rocker arms for 408 build

There are other links that cover Magnum components and durability etc. If you had the oem magnum rocker arm set up already I’d run them, or if not and better yet I’d be looking at the Mopar Performance rocker kit if you can actually get them. They’ll be reliable I’d think with less parts involved for what you’re looking for IMO. Here’s one link with some simple thoughts on the matter that maybe others can debate as to validityMagnum Horsepower - getting all the power from your Dodge 5.2 or 5.9 engine. |

Rocker Arms
Owners of LA smallblocks were spoiled for years by the old school Mopar’s use of shaft rockers. Sadly, this did not continue. On Magnum engines Chrysler opted for a pedestal rocker arm system very similar to what Ford used on 5.0 Mustangs.

Though many enthusiasts have reservations about them, we have spun the stock rockers to 6500 RPM regularly without failure. They are stronger than they appear. For more serious racers, there are aftermarket replacements available from numerous sources, and there are kits to convert the bolt down “pedestal” style rockers to “stud mount,” enabling Magnum owners to use cheap Chevy-style stud mount rockers. Our advice is to stick with the stock stuff for anything but an all-out race effort.

Thanks. That's one vote in favor of my current position.
