Windage Tray

I was reading the Smallblock stroker book earlier and they say the windage tray was designed for the 318/340's. And it was not recommended for use with a 360??? Made me think about pulling my pan. They also say with a 4" stroker crank you could lose up to 43 hp. The book does recommend using the Moroso pan. without it. The book is, How to build big-inch Mopar small blocks.
Don't shoot the messanger, they wrote that not me.
Anybody here ever test that on the dyno?
