Quote: How good or bad is the air speed with that much port volume Brett? Thanks for the pics.
Air speed is still fast this port was on the 2011 engine masters 411ci 535 of TQ at3500 rpm. In the big picture the port is still small 3" at port opening
Over 320feetper second down center of port
380-425FPS over short turn.
You can have large lazy port or larg port that is designed properly that for the most part has a much more Homogeneous flow floor to roof
