700 is not bull shit with factory heads ( squareports ) and a blower
What's the most horsepower someone, or anyone has made with Cast Iron OVAL factory heads on a BBC?
My friend's tellin me he makes 700hp out of a 468BBC and stock way ported OVAL heads so I wasn't sure if I should put my BS boots on.
So just wanted to hear some rumors? Anyone?

HB Jet is making over 700 with cast ported heads on a 496 I believe....

On a hot dyno.
If the ovals are somthing like bb2o extras
700 is possible, but will entail a lot of good porting work, and very careful parts selection.

your jealousy isn't becoming. Fact of the matter is the enging kicks ass and propels his boat(s) to ranges where that power is needed to go those speeds, end of story.
