was wondering if it is possible to do a cam and head swap on a 2003 350 mag mpi .. i was wondering if the ecm will be compatible ... i have the "555" ecm and from what i have read , whipple is the only company that messes with them but i dont want to go that route ... i like the turn key reliability but .... lol .... am looking for a little more ... :yes: has anyone done a few mods to theirs short of supercharging ?

I would imagine that it would work well along with beefing up the exhaust. I would bet that the good people at SM could set you up with a riser that was nice and dry.

I don't really know anyone that messes with the 555. Eddie Young and Tyler Crocket take them out and pin in a MEFI 4. I think that whipple goes that route as well.

Do let me know how it works out. Why is he going to a 5 blade? Is he getting that much slip with a shorty?
