can i install it with the distributor on?

hey guys
I just got my 408 back from MRL performance and I'm going over the last little ends that need to get tied up before I drop it in

the car is a 71 duster with the radiator removed

the engine is a 75 LA with a 727 transmission already attached, stock oil pan, internally balanced and NO pulleys installed

can I drop this combination in without removing the distributor?

I know when I did it last time there wasn't enough room BUT I also had a different oil pan and pulleys and belts installed already

oh, if it matters, I will also bolt up a set of dougs headers


thanks guys
