Nice Ross love the torque. If I’m reading it right not a very big cam for a 511. 5900 RPM should be pretty indestructable

Holy hell, that’s a great build.  As stated, it’s not turning much rpm!!!  Torque is impressive, this thing runs with good 460 strokers with similar specs. TFS are great, obviously, but the ported ones really seem to take advantage of the cleaned up flow past the stockers stall point.   

What year Merc?  Imagine some type of scoop is needed for the Victor…
