What drives the fuel pump on a Y Block?  Does the pump arm ride on the cam or is there a pushrod or something?  I can't picture it and none of my reference material is helping out, much.  

What do you think of NGK 2438 plugs?

I have used the NGK 2438 18mm spark plugs in a stock but blueprinted Ford Y engine and they worked just fine and held up well over time.  That engine had electronic ignition which helps with the overall life of the spark plugs.  That same NGK spark plug has also been used successfully in a stock iron headed 390 Ford engine also with electronic ignition.  The only issue I have with the 2438 NGK sparkplugs is that it’s a 'fit all' spark plug and only available in one heat range.  For a performance Ford application requiring a 18mm plug, a colder heat range spark plug would be desired.

How did we get from fuel pumps to spark plugs on this message?
