Ford 427s … So my port side is not getting enough fuel (idles but does not run under load), fuel pump is working so this dang fuel filter canister won’t turn .. do I need to remove the drain nut on the bottom?

    Fuel pump diaphragm…replace the fuel pump. You might think it’s working but if fuel drains into the oil…which it will you will lose an engine bearing.

    All fuel pumps have a test usually 15 seconds, which they must flow a certain volume.
    Forgo that, replace both engines pumps, and upgrade your filtering systems to new, up to date ones.
    Problem solved.

    Yes remove the plug and use a wrench on the bottom to remove the body.
    The filter inside is made of spun metal and is easy to clean. What about the short flexible hose that’s upstream of that filter that connects to your metal fuel line?

    It’ll turn. Put a big wrench on that square part at the bottom and turn lefty-loosy. It could still be the fuel pump. There may be a crack in the diaphragm that would allow the engine to idle, but not run at higher rpms. I went thru several fuel pumps during my 427 days.

    As a child, I recall the Ford 427 engine used in stock car racing. Ford had so much trouble holding the tolerances that engine required that they never sold more than the minimum required to the public. Does anyone have information about this engine? How did this compare to the 430 engine that I believe could be traced to the Lincoln?

    No comparison. The 430/431 had a novel block/heads arrangement. The block had an angled cylinder system. The 427 had so much more potential. Think Cobra, GT40, Chris Craft Supersport, etc. monster engine.

    I had luck isolating an issue like this by flipping my source fuel tanks to run both engines from same source as “good running” engine, similarly I also swapped carbs when trouble shooting. Helpful in determining exactly where issue was so I could repair it
