Brian6pac, if I could make a suggestion from experience please? You're gonna want to get a longer external oil hose. And use 45 degree fitting off the pump. Loop it upwards then back down to your pan 90 turned almost straight in the air. If you using a motor plate it looks like it will fit easy. What happens is your pump will lose its prime overnight with it pointing downwards. Which leads to either dry start or cranking the hell out of to get oil pressure before you start it. (Hard on starters) Just a suggestion. Sorry to hijack
