Choosing A TB For A Magnum

you can order the throttle plates (although it has slipped my mind right now on where, I think ebay though) and you can hone out you factory throttle body to 52mm without issues.

yes you can, but one 50mm might flow more than anothers 52mm, no different than modded carbs or ports.

not shooting you down as i'll probably be getting one of the ebay ones, just need the CFM i need first.
