I always hear the 4.6 being called the modular motor and naturally the 5.0 being the pushrod. A buddy of mine at work whom owns a 03 cobra we always give each other a lil **** talk here and there and he asked about if there was ever a modular 5.0 I said I don't think theyve made one but it both kinda made us curious if there ever was. Which also brought us to wonder what exactly is the diffrence between the pushrod style motors and the modular. So if anyone is willing to brush us up on some knowledge and give a little schoolin it would be appreciated.
