Oil pressure drop under hard braking

------------------------pan isn`t quite right inside, you answered ur own question, about uncovering the p/u. believe it or not, my swinging p/u will do it , if its a qt. low !

Did you use the 170 oil pick up tube also?

Since the engine originally came from a Charger, I swapped the 170's pan and pickup. I'll probably add a half quart for now, and at the next oil change, I'll run the borescope through the drain hole and see if anything looks obviously amiss.
