Putting the pickup in the notch seems too high in my opinion.

I use either a ball of foil or modeling clay to determine the clearance. Never had any issues doing it that way.

My experience is with 13-second daily driver street engines and low 12-second bracket race engines usually not spinning much more than 5500 rpm using the 60 psi Melling pumps. Never welded the pickup in place or used any support strap.

I drilled and tapped the pickup tube and pump body where they mate to secure the pickup, 10-32 socket head cap screw installed using red Loctite. My latest engine (mostly stock/restored 421 HO) was built by a friend who prefers to tack weld the pickup, he has built numerous engines for himself and other friends with no issues so I had no problem with his method of securing the pickup.

Upon further inspection, I came to realize that the cover plate lip at the notch overhung quite a bit, so I came to the same conclusion. But I still wanted to hear the opinion of the pros before doing any grinding so thanks for the input.

b-man, I fabricated a bracket to hold it in place. Scroll down a bit and you'll see pics. I'll be drilling holes in it yet to weld to.

Thanks again guys!
