Ported Magnuson 2650’s have seen 60-80 RWHP gains over non-ported with the same pulley’s, but the ceiling is MUCH higher if you have the fueling and belt under control, and then the engine to survive it. If stock block, you will need to sleeve it to fully utilize a ported Maggie 2650 (I know first hand).

It's LME's block, rated 1400. Kong told me recently that ported Eddie and Maggie are close in hp. I don't think my hpfp will support another 100 hp but Stanadyne's will. Adding more fuel is simpler than adding more air.
