Hay Tom, I'm building it for a blown 540 aroung 1000hp. It has a Dominator Split bowl. I'm also looking for a droop and a loader grate It has no grate right now. Its a lake boat but want to see 100mph I want to move the pump back so I can gain Back some of the room that the blower pulley is taking up. Not a lot of rear room so all that is lost is lost. I've got two kids that have to ride back there. Thanks for all of the help!
