Big Block Oil Pan for A body Swap ?

Been running a current MOROSO 7.5 quart pan and windage tray in the fish and it fits and works well. A bit of rub on hard right turns but not really an issue for the last 6 years. I bought the repo 893 and pickup as soon as they came out years ago for future plans. When I find the original grind RR cam to go back in then the 893 will go on. It took years to get on the road, so it has not been a hurry to totally correct it.
