Does anyone know where to get the roller cam bearings for a 440.

What size are you looking for? Todd

Standard size cam bearing diameter surrounded by roller bearings. Have seen them for Chevy but not mopar yet.

I don't think you'll find such an item since it would require 5 different cam bearings.

Every Mopar that I've seen converted over to roller cam bearings uses larger bearings such as 52mm, 55mm or 60mm roller bearings.

And they require special cams as well and lets just say wait till you try calling around to find them. Expect to pay close to 750 or more dollars and waiting two to three months to get them. These are really an item for the most extreme engines. FWIW
