Agree. After I switched to his oil pump my issue stopped.
My Luhn pump is this design:

I might note his pick up design as I pictured was a modified unit from a late model Mustang Cobra, it's no longer available so he now makes his own design as Tom posted.
I use a Canton 15-450 pan that was custom modified by canton with a deeper sump to increase the capacity, also the previous Canton oil pick up was properly adjusted for the increased depth.
Same oil pan now, same baffles, same trap doors... now with the Luhn pump and it's stable oil pressure no matter how hard you hit it !
