    Finally pulled the tired 4.6 out of my 99 GT and went out and bought a ford racing aluminator short block thinking about throwing some 03/04 cobra heads on it and for now a factory eaton supercharger. Will the compression of my block be ok for a factory supercharger???

    I believe you have to do a full ecu harness swap to go from 2v to 4v. What you could do with that block is put a kenne bell on it or run a centrifugal sc or go tork teck.
