[REDRIDDER]

Has anyone ever done this to a stock 400ex if so what were your power gains like and what kind of port and polish job did you do?Yes i know why am i asking when mine is ported & polished,because i got a lot done all at once so its hard to tell let me here your inputs like were you got it done how much any dyno charts of before and after .

Port and Polish is hard to judge because every engine builder is different, so the gains I got will be different then you because of all the variables. I'd say talk directly to the engine builder that has done your port and polish and see if they have numbers.
