I have a 350 mag bravo 3 21' maria that froze last winter. I am rebuilding it and want to build more power this side of a 5k Procharger kit.

Doe's anyone have suggestions or have done this. I do not what cam it comes with but have all other specs. I would like to at at a bare minimum pistons with higher compression, cam, rollers. I want to do as much as I can to it and still keep reliability. I usually run 3000 plus RPM Thanks a million

Make it a stroker.
383 sounds about right
